Defensive end Jadeveon Clowney ran a 4.47 40-yard dash at the NFL scouting combine in Indianapolis on Monday, according to multiple reports. He ran a 4.48 on his second attempt.

It was later reported that his official time was 4.53.

The former South Carolina star predicted impressive numbers, and he delivered with a time that was faster than 56 running backs and wide receivers who ran the 40 on Sunday, according to ESPN's Rich Cimini.
