If you remember the name D.J. Hayden, chances are you remember it because Hayden was the victim of one of the most terrifying and unusual injuries ever suffered by an athlete.
Four months ago Hayden, a defensive back at the University of Houston, ruptured the main vein to his heart during a practice. Doctors said this kind of injury is normally associated with car accidents and is fatal 95 percent of the time.
Monday, Hayden ran a 4.33 40-yard dash in front of representatives from 27 NFL teams at Houston's pro day.
Hayden's injury makes him a unique case, obviously. His injury had never been reported as a result of playing football before, so his situation is a lot different from someone with a torn-up knee or a heart condition. He attended the NFL Scouting Combine earlier this month, but didn't work out.
He's a good prospect, too. He had four interceptions last season before his injury and is thought to be a potential mid-round selection in the NFL Draft.
