Costly win for Browns

The Cleveland Browns' big win over the Pittsburgh Steelers on Sunday was dampened by an injury to Pro Bowl center Alex Mack.

Mack, who had never missed a snap in his pro career, broke his left leg during the 31-10 victory.

He was injured while blocking on a running play in the second quarter and was face-down on the turf for several minutes before a cart was brought out to drive him to the locker room.
