McGahee remained down on the field after being tackled on a 1-yard run late in the first quarter by Seattle linebacker Lofa Tatupu and defensive tackle Brandon Mebane. McGahee walked slowly off the field, and had his chest wrapped on the sideline before walking back to the locker room.

The team said McGahee was hopeful of returning in the second half, but was announced as being out when the second half began. After the game, the Ravens said McGahee had cracked ribs and his status for next week's season finale against Pittsburgh was unknown.

McGahee had five carries for 10 yards in the first quarter. Former Denver lead running back Mike Anderson took McGahee's place. Anderson had seven carries for the season entering Sunday, but was also slowed by a hamstring injury in the second half.

Baltimore was already without middle linebacker Ray Lewis, and its top two tight ends and cornerbacks. Offensive tackle Jonathan Ogden also strained his left hamstring in the first quarter, but remained in the game until the closing minutes.
