Hurdler Lolo Jones trash-talked about head injuries to former Rutgers football player Eric LeGrand after he jokingly challenged her to a race on Twitter.
What she didn't know was the defensive tackle was paralyzed in a game.
After LeGrand tweeted to Jones "want to race me?" on Tuesday night, she replied: "Get Checked for a concussion. Clearly, u've been hit in the head . . . Cos u arnt beating a track athlete."
When other users informed Jones of LeGrand's injuries, she wrote: "Great I'm gonna get murdered for that tweet. When I had no clue who that dude was. Just responding to any athlete who challenges me to a race."
