Donte Stallworth wins the "Strangest Off-Field Injury for an NFL Player" award for 2013
Stallworth was in the hot air balloon somewhere over the Miami area, and it crashed into some power lines. Two of the passengers, thought to be Stallworth and his girlfriend, were hospitalized.
This is definitely the most bizarre injury of the offseason so far, but you never know. There's always a chance that Manti Te'o can strain a ligament while getting down with his imaginary girlfriend, right?
For now, however, Stallworth takes the cake.
