Broncos declare Welker out

ENGLEWOOD, Colo. -- As expected, the Broncos formally designated wide receiver Wes Welker as out for Sunday's game in Houston.

Welker is also expected to be held out of next week's regular-season finale in Oakland as he continues to go through medical evaluations for a concussion suffered Dec. 12 against the Tennessee Titans. It was the second concussion Welker suffered in a four-game span.

Welker has not practiced with the team since, though he has begun light physical activity in recent days.

Defensive end Derek Wolfe (illness) and cornerback Kayvon Webster (right thumb), who like Welker have not practiced this week, were also ruled out of Sunday's game.

Webster, who had surgery to repair a fracture last Friday, is expected to practice at least on a limited basis next week with a cast on his right hand. He is also expected to play with the cast against the Raiders and into the postseason.

“Everything's good," Broncos head coach John Fox said of Webster following Friday's practice. "... He missed this week because he is recovering from an actual surgery, don't want to risk any infection ... but I think next week there is more of an opportunity in a cast he could be able to play."

The Broncos are optimistic on Wolfe, who has not practiced since suffering seizure-like symptoms Nov. 29. He will return for the postseason as well. Like Welker, Wolfe has done work with the team's strength and conditioning staff in recent days.

Everyone else listed on the Broncos injury report this week, including cornerback Champ Bailey (left foot), was designated as probable and is expected to play Sunday against the Texans.

Bailey has said he's "ready to go."
