Parker leaves after breaking right fibula in first quarter

ST. LOUIS -- Pittsburgh Steelers running back Willie Parker, the NFL's leading rusher, broke a bone in his lower right leg in the first quarter Thursday night of a 41-24 win over the St. Louis Rams.

Parker, who entered the game with 1,317 yards and consecutive 100-yard games, had one carry for a 1-yard loss before leaving the game. X-rays revealed the injury to be a fractured fibula.

Najeh Davenport, who entered the game with 349 yards and a 4.9-yard average, replaced Parker in the lineup.
