That means former Washington receiver John Ross still has the record at 4.22, which he set in 2017.
Ruggs, who ran a 4.31 on his second attempt, will have to settle for one of the 10 best official times in NFL Combine history. It’s among the fastest times by a receiver along with Ross, Jerome Mathis (4.26) and Marquise Goodwin (4.27).
Ruggs suffered an undisclosed injury on the second run.

He false-started on his first attempt before running what was initially timed a 4.28 40. He looked visibly upset afterward.
Ruggs still increased his draft stock with the strong performance. He averaged 17.5 yards per catch with 24 touchdowns as a home-run threat for the Crimson Tide the last three seasons, and he is projected to be a first-round pick in Sporting News’ latest mock draft.
