12Danny Amendola
This guy was one of the lucky ones. In 2011, Danny Amendola was the No. 1 receiver for the St. Louis Rams, and in his opening game of the season he fell to the ground, ironically on his own, and had his elbow buckle underneath him. That was it for him because thanks to a bad elbow dislocation he ended the season before it actually started. The good thing is that he managed to return to full glory once he got back onto the field the following season.
