Former NFL players Tony Scheffler and Sidney Rice both announced their retirement over the summer and both players retired for largely the same reason: Concussions.

Broncos wide receiver Wes Welker never seriously considered retirement after suffering his third concussion in 10 months in August, but one of Welker's former teammates would probably hang up his cleats if he suffered a third concussion.

Jessie James Decker, the wife of Jets wide receiver Eric Decker, said this week that she'd want Eric to stop playing if he suffered three concussions.
