The worst injury I had happened at a 24 hr edmonton game. It didn't seem so bad untill towards the end of the game when it was getting progressivly worse. The heel on my boot collapsed and the stress on my akilies tendon for the remainder of the game made it extremely difficult to walk for the next month. I even had to hitch a ride on one of the clean up trucks to get off the field. Turns out I had micro tearing.
