According to TFY Draft Insider:
Kansas State LB Arthur Brown ran forty times in the 4.58-4.62 range at the Wildcats' Pro Day.
Brown didn't work out at the Combine due to a shoulder injury. He proceeded to "blow up" his Pro Day workout, according to NFL Draft insider Tony Pauline, tipping the scales at 6-foot-1, 236 and repping 225 pounds 21 times on the bench press. He was reportedly "sensational" in drill work. Writes Pauline of Brown, "We are hearing late-first round is now a possibility."
