Football definitely left its mark on me.
In highschool, I tore a hole in my rotator cuff and cracked two knuckles. To this day I can't toss a football around too long without my shoulder getting really sore.
In Junior football after highschool I really did some damage. First game I got chopped square on the front of my knee. Bad hyperextension which stretched all the ligaments in my knee and left me with a lot of cartiledge (sp?) floating around. Surgery wasn't an option as I didn't actually tear the ligaments, so I did a little physio and now I wear a brace with metal supports whenever I'm working out. Silly young football player that I was, I only missed one game. I wrecked my neck as well, stretched the muscle between my neck and shoulder to about 4 times its intended purpose. This is all according to our trainer as I never bothered to see a doctor about it. Dislocated a hip too, which was amazingly painful until I stomped it back into place. I blame a lot of this on the crap quality of junior football as I took a lot of shots I wouldn't have had to if I had some decent players around me.
In University, playing on a proper team with proper coaching, I didn't do anything too terrible to my body. Type 1 (I think) hyperextension in my right shoulder but that wasn't a big deal.
Basically my body is a bit of a mess and is really gonna get me back when I hit mid age. Nothing I can't walk off though.
