Pittsburgh, PA (SportsNetwork.com) - The Pittsburgh Steelers will likely be down a pair of defensive starters for their pivotal Thanksgiving Day clash with the Baltimore Ravens.

Nose tackle Steve McLendon has been ruled out for Thursday's contest due to a left ankle injury he sustained in Sunday's 27-11 win at Cleveland, while outside linebacker LaMarr Woodley is listed as doubtful as he continues to recover from a strained calf.

Woodley has missed Pittsburgh's last two games with the issue, with Jason Worilds drawing the start in his place. Al Woods is expected to fill in for McLendon in the base defense.

On a positive note, veteran end Brett Keisel is probable to face the Ravens after sitting out the past two games with an injured foot. The 35-year-old participated fully in practice during the week.
