During his second attempt at the 40-yard dash at the NFL Combine, Cardale Jones suffered a hamstring injury. 

According to Kimberly Jones of NFL.com, Jones is "done for the day." In his first attempt, the former Ohio State quarterback ran an unofficial time of 4.83 seconds which, given his 6-foot-5, 250-pound frame, isn't bad at all. 

After seeing limited time on the field in his junior year with the Buckeyes, Cardale probably wanted to make the most of the Combine. Even though Jones won't be able to participate in the Combine, he will be able to win over NFL teams at Ohio State's Pro Day on March 11 and any private workouts. That is, as long as the injury isn't serious.

Oh, and while we're discussing the Combine, let's just leave this right here.
