Firstly let's clear one thing up - Tom Trbojevic, Braidon Burns, Matt Moylan and now Andrew Fifita, currently are suffering tears to their hamstringS (plural) and not hamstring (singular).
This troublesome injury, which is the second highest for running sports (cyclists and swimmers don't suffer them) behind calf tears, is not a single muscle.
It is a whole group of them and where they begin and end in your body might surprise you.
Secondly, a leading sports physician who has been part of Australian teams at the Commonwealth Games, Olympic and Paralympic Games – Dr Geoff Thompson – says torn hamstrings should be regarded more like ACL tears and dislocated shoulders.
By that he means they should be seen as long-term injuries and not rushed back too early.
"There's pressure that comes from all quarters, especially at professional level, like clubs, coaches and the players themselves to get back on the field," he said.
