Wolfe's name appeared on the transaction report that each team receives daily from the league office, and the Broncos announced the move later Tuesday.
Wolfe was not expected to play in Sunday's AFC Championship Game, but the Broncos had continued to express at least some optimism in recent weeks he could at least return to the practice field before their season ended. Wolfe was the only player on the roster who did not practice last week in the days leading up to Sunday's 24-17 victory against the San Diego Chargers.
Wolfe had practiced just twice since Nov. 29 when he suffered "seizure-like symptoms" 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.
He did not practice since then as doctors continued to monitor him and try to trace the origins of the seizure symptoms. Team officials, including coach John Fox, have repeatedly said "the big stuff" had been eliminated as causes, but that it was more likely a combination of factors that could include diet, sleep issues and stress.
Wolfe had appeared far lighter than his listed weight of 285 pounds in recent weeks. Fox has spoken of the need for Wolfe to be cleared by the medical staff and then regain his conditioning before he could return to practice full time.
The Broncos signed former Jacksonville Jaguars defensive end Jeremy Mincey last month, and Mincey has been in the rotation in the defensive front since, working at end with Shaun Phillips and Robert Ayers.
Also Tuesday, the Broncos put cornerback Chris Harris, who suffered a torn ACL in last Sunday's game, on injured reserve. With the two available roster spots, the Broncos signed cornerback Marquice Cole, a former New England Patriots defensive back, and elevated tackle Vinston Painter from their practice squad.
Painter was a sixth-round draft pick by the Broncos last April and had spent the entire season on the team's practice squad.
