The Denver Broncos have been without some key starters so far this preseason, but several of them are coming back to practice this week.

The Denver Post writes that five injured Broncos returned to action yesterday, including running back Correll Buckhalter, cornerback Champ Bailey, right guard Chris Kuper, rookie wide receiver Demaryius Thomas, and linebacker DJ Williams.

Left tackle Ryan Clady, a key piece of the offensive line, and running back LenDale White will also return to practice today. It’s unclear how many of them will play against the Pittsburgh Steelers in this weekend’s third and most important preseason game.

But at least one player is unlikely to ever return to Broncos practice after being cut from the team yesterday. Tyler Polumbus, an offensive lineman, starred at Cherry Creek High School and the University of Colorado but went undrafted out of college. The Broncos signed him in 2008, and he started eight games in 2009 in place of right tackle Ryan Harris.

Polumbus apparently didn’t transition well to the Broncos’ new power-blocking scheme, according to Mile High Report, but The Denver Post reports that he could land in D.C. with former Broncos coach Mike Shanahan or in Houston with former Broncos offensive coordinator Gary Kubiak.
