KANSAS CITY, Mo. -- Alex Smith threw for 225 yards and two touchdown passes, and the Kansas City Chiefs held off the scrappy Cleveland Browns late in the fourth quarter to preserve a 23-17 victory Sunday and remain the NFL's lone undefeated team.
Jason Campbell, starting in place of the ineffective Brandon Weeden, threw for 293 yards and two touchdowns for the Browns.
Campbell's second scoring pass, a 17-yarder to Fozzy Whittaker out of the backfield, got Cleveland within a field goal early in the third quarter.
The Chiefs kept stopping the Browns down the stretch, though. They forced a turnover on downs with just over 2 minutes left, and Ryan Succop kicked his third field goal in the closing seconds to help seal the victory.
