Brett Keisel reaggravates hurt foot

BALTIMORE -- Pittsburgh Steelers defensive end Brett Keisel left the Thanksgiving game against the Baltimore Ravens after reaggravating a foot injury that had sidelined him the previous two weeks. He was ruled out and did not return to the Steelers' eventual 22-20 loss.

Keisel played only a couple of snaps before giving way to Ziggy Hood at right defensive end.

The Steelers already were without two defensive starters, as outside linebacker LaMarr Woodley and nose tackle Steve McLendon are sidelined with calf and ankle injuries, respectively.

Jason Worilds continues to excel while filling in for Woodley at left outside linebacker. Worilds had two sacks in Thursday night's game, including one that forced the Ravens to settle for a field goal and a 10-0 halftime lead. The Ravens improved to 6-6 and dropped their fierce rivals to 5-7, in addition to snapping the Steelers' three-game winning streak.

Worilds now has a team-high six sacks, one more than Woodley, the highest-paid defensive player in Steelers history.

Woodley has missed three games in a row.
