Jonathan Jones' blazing speed was on display Monday morning at the NFL Combine.

Jones ran a 40-yard dash time of 4.28 seconds in his first attempt. The time is unofficial for now, but it's extremely fast, obviously. He posted a time of 4.33 seconds on his second attempt.

Update (9:30 a.m. CT): Jones' official 40-yard dash time is 4.33 seconds, the fastest time among the defensive backs and the third-fastest time at the NFL Combine this year.

The time of 4.33 is tied for the second-best time by an Auburn player since 1999.
