The Most Common Football Injuries, Explained

An ankle sprain describes the stretching or tearing of the ankle's ligaments, the tough bands of fibrous tissue that connect two bones together in your joints. "This can happen when landing from a jump after heading a ball or when involved with a slide tackle", Mack said. Even tripping on the pitch can lead to an ankle sprain, Williams said.

Treatment usually involves immobilising your ankle with a brace, Mack said, along with ankle strengthening and rehab once the initial injury has healed. In more severe cases, someone may need to use crutches, she said. But, "depending on the grade of the sprain, it's possible the athlete won't have to take any days off entirely, but they may need to avoid [physical] contact for a few days", Isaac said.

A calf strain is a stretched or torn muscle or tendon in the calf. Strains can happen suddenly or develop over time and tend to cause symptoms like pain, muscle spasms, swelling and trouble moving the muscles. Calf strains tend to happen due to "inadequate warm-up", Isaac said, but getting older and having a history of calf strains can increase your risk.

Recovery from a calf strain largely depends on how severe it was, Isaac said, adding, "it can be as little as four to five days and as much as 45 days". Treatment usually includes "rest from sprinting or other explosive movements" and rehab to strengthen the injured muscle, Mack said.

A foot fracture is a partial or complete break in one of the bones of the feet, according to Cedars-Sinai Medical Center. "This can be from overuse, like a stress fracture, or traumatic, like someone stepping on your foot or landing from a jump in a less-than-optimal position", Williams said. Treatment involves "some sort of decreased weight-bearing for a period [of] time" and possibly even surgery, he said. After that, Williams said, someone will need rehabilitation to restore flexibility, mobility and strength before getting back on the pitch.

Kneecap bursitis is a painful condition that impacts the bursae, the small, fluid-filled sacs that cushion the bones around the kneecap, the Mayo Clinic explained. This "can occur from the constant stopping and starting that players have to do on the pitch", Mack said. Treatment usually requires rest, ice, compression and elevation, Isaac said, along with physiotherapy treatments like soft tissue massage and strengthening. "Compression sleeves can be used to help with swelling", she said. And, in some situations, a doctor may need to extract excess fluid.

"There are a handful of ligaments in the knee that can be sprained and the mechanism of injury to each ligament is a little different", Isaac said. "The ACL is most commonly injured by a sudden twisting motion with a planted foot, while the MCL, PCL and LCL are most commonly injured due to a direct blow to the outside, back or inside of the knee, respectively". And treatment wildly varies depending on how severe the sprain is, she added.

For more minor injuries, rest, ice, compression and elevation may help, she said. But, for more severe injuries, surgery may be needed. Eventually, a person would progress to physiotherapy, where they work on regaining strength and agility, Isaac said.

The clavicle, otherwise known as the collarbone, is the bone that connects the breastplate to the shoulder, according to the American Academy of Orthopaedic Surgeons. This fracture "is a traumatic injury, whether by fall or a very targeted blow to the clavicle region", Williams said. Treatment focuses on immobilising the area with a splint and sometimes surgery is needed, Mack said. The goal through treatment, Williams said, is to restore range of motion and strengthen the arm.
