(Reuters) - The Houston Texans overcame bitterly cold conditions and driving rain to beat the Chicago Bears 13-6 on Sunday in a gritty clash between two of the top defenses in the NFL.
Playing through the cold conditions at Chicago's Soldier Field, the Texans (8-1) traded hard-hitting blows with the Bears and prevailed to remain top of the AFC and prove their title credentials.
Arian Foster fought for 102 yards rushing and caught a two-yard touchdown pass in the second quarter for a 10-3 Texans lead that stood out in a game that featured little offense.
Chicago quarterback Jay Cutler was knocked out of the game with concussion late in the second period after taking a hard hit that forced him to stay in the locker room at halftime.
Backup Jason Campbell could only lead the home team to a third-quarter field goal against the determined Houston defense while the Texans added a field goal in the fourth from Shayne Graham, his second of the game.
Chicago's final drive attempt to tie the game stalled at their own 40-yard line.
Though the Bears (7-2) entered the game as the league's best at creating turnovers, the Texans outshone them with four, including three in the first quarter.
