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. Jones didn't know 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."

LeGrand later tweeted: "didnt take it personal,understand where ur coming from.All good."

LeGrand broke two vertebrae and suffered a serious spinal cord injury in 2010 against Army.
