I nominate Aaron Lockett at USC.
It was a cheap shot but did he get hurt?
Josh Moore's was scary if not nasty. Jermaine Moreira vs CU. For a second there I was like "YEAH, AND STAY DOWN DUMBASS!" ..."oh, @#%$."
Moore and Moreira are both at the top of my list. I was there for the Moreira one but not the Moore one. All I remember thinking after the Moreira hit was "I'll never think this is cool on TV ever again".
Slaying of Allan Everidge at TT.
I forgot about that one!

Pretty much, If Chad May were on here he'd be griping about getting punched in the yam bag at NU. I thought it was getting poked in the eyes by NU in Manhattan.
I don't remember him getting punched in the "yam bag" but I remember the eye poking. It's even worse when you see it on the replay.
Didn't Hickson snap his leg in half?
He got hurt during a "Fan Appreciation Day". Along those lines I remember when Eric Gallon got hurt and was supposed to be out for a VERY long time. He was back at the beginning of the next season if I remember correctly. My very first "Superman" moment at a KSU football game.
