OWINGS MILLS - Pro Bowl right guard Marshal Yanda missed practice Wednesday with the seriously sprained right ankle he suffered against the Redskins, but center Matt Birk voiced optimism regarding Yanda's availability for Sunday.

Birk referenced Yanda's return from a nasty calf injury he suffered against the Browns last December. Yanda was forced to undergo emergency surgery after the game, later describing a procedure that required doctors to "slit the muscle open" to relieve pressure. Yet, a week later, Yanda was in the starting lineup for the Ravens' regular season finale against the Bengals.

"It's only Wednesday. We'll see how it goes," Birk said. "But, you can check, he's traditionally been a pretty fast healer, like when he had to have his leg sliced open and was playing a week later, so we'll how it goes."

Yanda sustained the ankle injury on Baltimore's second offensive play of overtime when Redskins defensive lineman Barry Cofield fell onto the back of his right ankle while being blocked to the ground by Birk.

Yanda remained on the ground for several minutes in noticeable pain before being helped to the sideline.

He was on crutches after the game. The crutches were gone Wednesday, but he was in a walking boot.

Yanda has started 51 consecutive games, including all 13 this year.

If he's unable to play, veteran Bobbie Williams would likely replace him at right guard. Williams stepped in for Yanda after Yanda got hurt against the Redskins.

Williams has played in 11 games this season and made four starts at left guard.

"If [Yanda's] not able to go, that's unfortunate, but we've got great guys," Birk said. "Bobbie's played a lot of football and he can step in there and do a great job."
