Ross, who played at the University of Washington and Long Beach Jordan High, covered the distance in 4.22 seconds, breaking the record of 4.24 set by running back
"I feel like I could have run faster," Ross told the NFL Network.
Adidas announced before the combine that it would provide an island to a player who broke the record — if he did it while wearing Adidas cleats and agreed to an endorsement contract with the company.
Ross blazed to the record while wearing shoes made by Nike.
Ross said this week that 4.3 seconds was his previous best time in the 40. Asked if he could break Johnson's record, he said, "I am going to try. I don't want to say too much. I'm going to try. I'm going to give it my best."
Ross caught 81 passes, 17 for touchdowns, at Washington last season.
The record 40 time is expected to help boost Ross' stock for the April draft.
