Jerome Harrison broke Jim Brown's single-game rushing record of 237 yards Sunday at Kansas City.
With seconds remaining, Harrison had 286 yards, third best in NFL history behind Minnesota's Adrian Peterson (296) and Baltimore's Jamal Lewis (295). Harrison's effort came on 29 carries.
Harrison went over Brown's mark with a 5-yard run late in the fourth quarter. Then he followed with a 2-yard gain, which gave him 240 yards on 29 carries, before leaving the game.
Harrison became the fifth running back in Browns history to go over 200 yards rushing. That feat has been accomplished only eight times, four times by Brown.
Harrison's previous best in his four-year career was 121 yards against Cincinnati on Oct. 4, 2009. Harrison also recorded his first three-touchdown game, scoring on runs of 71, 28 and 28 yards. His 71-yarder was the Browns' longest run since he scored on a 72-yarder on Nov. 17, 2008 at Buffalo.
