Ankle Sprains: Prevention and Care

By 4Football Staff · October 12, 2026 · 10 min read

A guide to how football players sprain ankles, the difference between low and high ankle sprains, how severity is graded, and how balance work and bracing reduce repeat injuries.

Ask any athletic trainer which injury they see most often and the answer is rarely dramatic. It is not the torn knee ligament or the broken collarbone. It is the ankle that rolled on a cut, a teammate's foot or an uneven spot in the grass. The ankle sprain is common enough that many players treat it as part of the sport, shrug, tape up and keep going.

That habit is the problem. A sprained ankle that is rushed back into play is more likely to be sprained again, and repeated sprains can leave a joint that never feels quite right. Taken seriously, a sprain is manageable and usually recovers well. Taken lightly, it becomes the start of a long pattern.

This article explains what a sprain is, why football produces so many of them, how the common types differ, what the first days of care generally involve, and which prevention habits have the best evidence. It is general information. A physician or athletic trainer should evaluate any injury that causes real pain, swelling or difficulty putting weight on the foot.

What a sprain actually is

A sprain is an injury to a ligament, the strong band of tissue that connects one bone to another. A strain, by contrast, is an injury to a muscle or a tendon, which connects muscle to bone. The two words sound alike and are often mixed up, even by players and coaches.

The ankle joint is formed by the lower leg bones and the foot bone that sits beneath them. Ligaments on the outside, inside and front of the joint hold everything in line while still allowing the foot to flex and rotate. When the foot is forced past its normal range, one or more of those ligaments stretches or tears.

Why football produces so many sprains

Football combines the things that stress ankles most.

• Cutting and planting. Players change direction at speed with a cleated foot fixed in the ground.
• Contact from other players. A defender who falls on the back of a runner's leg, or a lineman whose foot is trapped under a pile, can force the ankle in a direction it does not go.
• Landing on someone else's foot. Receivers and defensive backs jumping for a pass can land on an opponent, which is a classic way to roll an ankle.
• Surface and footwear. Cleats that grip well hold the foot while the body moves on top of it. Uneven turf, a divot or a seam in artificial turf can do the same thing. Our article on grass vs turf injury considerations covers the surface question.
• Fatigue. Muscles around the ankle that tire late in a game protect the joint less well.

Low ankle sprains and high ankle sprains

Most people picture the same injury: the foot turns inward, the outside of the ankle swells and the player limps off. That is a lateral ankle sprain, often called a low ankle sprain, and it is by far the most common kind.

Lateral (low) ankle sprain

The foot rolls inward, which is called inversion, and the ligaments on the outside of the ankle are stretched or torn. These ligaments are the ones most often injured. The ankle swells, may bruise and is tender on the outside. Many of these sprains improve over a matter of weeks, though severity varies widely.

High ankle sprain

A high ankle sprain involves the ligaments that connect the two long bones of the lower leg just above the ankle joint. This group of ligaments is called the syndesmosis. The usual mechanism is the foot being forced outward and rotated, often when a player's leg is pinned or when a heavy body falls on the lower leg.

High ankle sprains tend to hurt above the joint, make it painful to push off or twist, and commonly take longer to heal than low sprains. Because they can destabilize the space between the two leg bones, doctors take them seriously and sometimes use imaging to check how much the ligaments are injured. They are one reason a player can miss far more time with what sounded like "just an ankle."

Grading severity

Clinicians often describe sprains in three grades. The exact criteria differ between sources, but the idea is consistent.

1. Grade 1: The ligament is stretched with minimal tearing. There is mild pain and swelling, and the ankle is stable.
2. Grade 2: The ligament is partly torn. There is moderate swelling, bruising, pain and some looseness in the joint.
3. Grade 3: The ligament is completely torn. There is significant swelling and bruising, the ankle may feel unstable and bearing weight is difficult.

Grade matters because it predicts how long recovery might take and whether a more serious problem exists. A trainer or doctor assigns the grade after examining the ankle. A player cannot reliably grade his own sprain from the sideline.

When an ankle might be more than a sprain

Not every painful ankle is a sprain. The foot and ankle contain a lot of small bones, and fractures can look like sprains at first. Clinicians use a set of simple rules, known as the Ottawa ankle rules, to decide when imaging is needed. The rules look at things such as tenderness over certain bony points and whether the person can take about four steps right after the injury and in the examination room.

You do not need to memorize the rules, but the principle is useful. A player who cannot bear weight, who has pain directly over a bone, or whose foot looks misshapen should be seen by a medical professional promptly. Numbness, a foot that looks pale or blue, or severe pain that is getting worse are reasons to seek urgent care. When in doubt, have the injury checked. Our article on the role of the athletic trainer explains how trainers make these sideline decisions.

The first days of care

Advice for early care has evolved over the years. The old shorthand, RICE for rest, ice, compression and elevation, has been refined and argued over, and some current guidance puts more emphasis on protecting the joint at first and then moving it early rather than resting it for a long time. Because the details are debated, the safest summary is this.

• Protect the ankle early. Avoid activities that cause sharp pain. Crutches or a brace may be used for a short time, depending on severity.
• Control swelling. Elevation and compression are commonly used. Ice is widely used for comfort. Ask the clinician what they recommend.
• Start gentle movement when it is safe. Many clinicians now encourage early, pain-limited motion rather than prolonged immobilization. Do not push through sharp pain.
• Get a proper evaluation. A trainer or doctor can tell you what grade the sprain is and how to proceed.
• Ask before taking any medication. Over-the-counter pain relievers have their own cautions, especially for young players, so check with a physician or pharmacist.

The goal in the first days is to settle the injury without letting the joint go stiff or the muscles shut down.

Rehabilitation: the part that prevents the next sprain

Once the pain and swelling settle, rehabilitation is what restores the ankle. Many sprains go wrong here, not at the moment of injury. A player feels better, stops the exercises and goes back to play with an ankle that has lost strength and, more importantly, lost the reflexes that tell the foot where it is in space.

Good rehabilitation typically moves through several stages.

1. Restore range of motion. The ankle regains the ability to flex and point the foot and to move side to side.
2. Rebuild strength. The muscles that surround the ankle, especially those along the outside of the lower leg and the calf, are strengthened with resistance bands and body-weight work.
3. Retrain balance. This is the stage most players skip. Standing on the injured leg, then closing the eyes, then standing on an unstable surface teaches the ankle to react quickly.
4. Add running and cutting. The athlete jogs, then runs, then practices cuts and changes of direction at gradually increasing speed.
5. Return to sport. Full practice comes last, and many clinicians want the athlete to pass some functional tests first.

The reason balance matters so much is that a sprain damages not only the ligament but also the nerve endings inside it, which feed information to the brain about the position of the joint. Training the ankle to balance helps rebuild that sense, which is why it is a cornerstone of both treatment and prevention.

The risk of repeat sprains

The single best predictor of an ankle sprain is a previous ankle sprain. A joint that has been sprained once may be looser, and a player who did not complete rehabilitation may have lingering weakness or poor balance. Repeated sprains can lead to what clinicians call chronic ankle instability, in which the ankle repeatedly gives way during normal activity and the player feels that it cannot be trusted.

The takeaway is not that a sprained ankle is a disaster. It is that finishing the rehabilitation is not optional, and that a team's sports medicine staff should treat a "minor" sprain with the same respect as a major one.

Prevention that has real support

Several habits reduce the risk of an ankle sprain, with the strongest evidence for people who have already had one.

Balance and neuromuscular training

Programs that train balance and control of the ankle, usually on one leg, have been shown in research to lower the rate of ankle sprains, particularly repeat sprains. A simple routine might include standing on one leg, doing the same with eyes closed, standing on a cushion, and catching a ball while balancing. These exercises can be built into a warm-up. Our article on injury prevention, warm-ups and prehab shows how.

Strength

Strong muscles on the outside of the lower leg, along with the calf and hip muscles, help control the ankle when the foot lands in an awkward spot.

Tape and braces

Taping and bracing are widely used in football. Research suggests that braces, in particular, can reduce the chance of re-spraining an ankle that has been injured before. They are typically less necessary for athletes who have never had a sprain, and they are not a substitute for strength and balance. Tape can loosen during a game, while a lace-up or semi-rigid brace tends to hold its support. A trainer can advise which option suits a given player and position, and some governing bodies have rules about braces under or over equipment.

Footwear and fit

Cleats should fit well and be appropriate for the surface. Whether higher-cut shoes help prevent sprains is something the research has not settled, and the answer likely depends on the player and the shoe. Our article on choosing the right cleats covers the fit and surface questions.

Fields and conditions

Teams can check the field before practice for holes, divots and loose seams and report hazards to the facilities staff. It takes a few minutes and removes an avoidable cause of injury.

Fatigue management

Because injuries rise late in practices and games, programs that avoid piling on conditioning work immediately before cutting drills may reduce risk. Coaches differ on how to do that, but it is worth thinking about.

Common mistakes

• Walking it off. A sprain that is ignored can be worse the next day, and a missed fracture can cause lasting problems.
• Stopping rehab when the pain stops. Strength and balance take longer to return than comfort does.
• Over-relying on tape. Tape is an aid, not a cure for weak ankles.
• Skipping the evaluation for "just a high ankle sprain." Those injuries benefit from a proper look.
• Rushing back for a big game. The stakes of a single game rarely outweigh a season of repeated injury.

Following ankle injuries as a fan

Ankle sprains show up constantly on professional injury reports, usually listed as "ankle" with a status such as questionable or doubtful. The live injuries page shows the current reports and their designations. For fantasy managers, keep in mind that an "ankle" listing can mean anything from a minor tweak to a lengthy absence, and the type of sprain matters. Fantasy managers can look up a specific athlete on the players pages. If you play recreationally, the Play section offers a place to start.

The short version

• A sprain is a ligament injury; a strain involves a muscle or tendon.
• Low (lateral) ankle sprains are the most common and usually recover in weeks; high ankle sprains involve ligaments above the joint and often take longer.
• Sprains are graded from 1 to 3 by a clinician, and an inability to bear weight, pain over a bone or a misshapen foot calls for prompt medical evaluation.
• Early care protects the ankle and controls swelling, then moves to early, pain-limited motion; follow the clinician's instructions.
• Rehabilitation, especially balance training, is what prevents repeat sprains and chronic instability.
• Balance training, strength work and, for previously injured ankles, bracing have the best support for prevention; field checks and well-fitted cleats help too.
