What is a hamstring injury?
According to experienced sports physician Dr Peter Brukner, there are three general forms of hamstring injuries. “Grade one is where a few fibres of the hamstring are torn, but the majority of the muscle is sill intact,” he says, using this description to classify Cousins’ injury. Grade two is where a significant part of the muscle is torn. Grade three is a complete tear, which is very unusual and tends to happen when you tear the muscle off the bone.
