ENGLEWOOD, Colo. -- Denver Broncos defensive end Derek Wolfe continues to work toward his potential return to the field, but he was held out of practice again Monday.

Broncos coach John Fox had initially said Friday Wolfe would “be back Monday,’’ but the team’s medical staff is still working with Wolfe and team officials said Monday afternoon Wolfe has had scheduled visits with physicians that have kept him from other team activities. Wolfe is not expected to play Sunday against the San Diego Chargers, but Broncos officials were quick to point out Monday they didn’t believe Wolfe had suffered a setback in his return and the team still has at least some optimism he will play if the Broncos continue to advance in the postseason.

They have not placed him on injured reserve despite having several opportunities of late when a roster move needed to be made.

"When he's cleared, he'll be back,'' Fox said. "That's all in the hands of the medical people.''

Wolfe did not take part in the team’s two practices last week during their playoff bye week. The Broncos will not release an injury report this week until Wednesday.

Wolfe has not played since suffering “seizure-like symptoms’’ Nov. 29 on the team’s bus ride to the airport for a trip to Kansas City. He took part in the Broncos’ Christmas Day practice, missed the next day with the flu and then practiced on a limited basis Dec. 27.

Those were the only two practices Wolfe has participated in since his incident.

Wolfe was then left home when the Broncos went to Oakland for the regular-season finale. The Broncos have put Wolfe through some conditioning work in recent weeks and the Broncos have seen enough to have kept him on the active roster to this point.

Defensive end Shaun Phillips was sent home Monday because he had arrived to work feeling ill and with a fever, Fox said. Phillips and Wolfe were the only players on the Broncos’ 53-man roster who did not take part in Monday’s practice.

Safety Rahim Moore, who has been designated for return from injured reserve, after surgery on his lower leg to alleviate bleeding in the muscle, is eligible to practice this week. Moore, however, did not take part in Monday’s practice.

By rule Moore could play in the AFC Championship Game if he is cleared by the team’s medical staff before then.
