Its coming up on 4 years, JV game (3 man game) I'm the FJ and on the second half kickoff, the return runner is making his way up the sideline towards me. His angling to the sideline and I see a defender closing in on him. I back away OOB on SL see the play as they (runner and defender) pass in front of me. I"m in good position, to see the hit, I turn, look, see it, the spot. I'm killing the clock when I get clipped. Now I have a artificial knee. It works better then the other.
