Wes Welker in uniform at practice

ENGLEWOOD, Colo. -- Denver Broncos wide receiver Wes Welker, who suffered two concussions in a four-week span, and defensive tackle Derek Wolfe, who has not practiced since suffering "seizure-like symptoms" on Nov. 29, were both in uniform for Wednesday's practice.

The Broncos adjusted their schedule for Christmas, moving meetings as well as the start of practice -- both usually in the morning on a Wednesday -- into the afternoon. Wolfe and Welker worked through largely noncontact drills during the open portion of practice as Wolfe quickly moved over to work with the team's strength and conditioning staff when the defense ramped up the tempo a bit.

Welker, who suffered a concussion just before halftime of the Broncos' Dec. 8 victory over the Tennessee Titans, has not practiced since that game and has been held out of the past two games.

Wolfe had not practiced since his incident, which occurred on the team's bus ride to the airport for the trip to Kansas City for the Dec. 1 game against the Chiefs.

Welker, Wolfe and cornerback Kayvon Webster were all formally listed as limited, although Wolfe is still expected to be held out of Sunday's game in Oakland.

"He's just in the process of getting back into it," said Broncos coach John Fox. "Football is a unique game, you can try to simulate different things in the weight room, in different areas, but until you get out here and start running around it's not quite the same. He's back out there, he's got everything under control, now it's just a matter of him getting back in football shape."

Welker, who also suffered a concussion in the Broncos' Nov. 17 win over the Chiefs, remains a major question mark for Sunday's game as he continues to work through the league's concussion protocol.

"He's still in the steps of the concussion protocol, and we're taking it day to day," said Fox. "It was good to see him out there."

Before he can play in a game, Welker would have to be declared symptom-free by both the Broncos' medical staff as well as a designated independent physician who has been approved by both the NFL and NFL Players Association.

Webster, who had surgery Dec. 13 to repair a fractured right thumb, returned to practice Wednesday sporting a cast on his hand. Webster did not practice last week or play this past Sunday against the Houston Texans.
