As expected, the Broncos have placed center J.D. Walton on injured reserve with a fractured/dislocated ankle.
Taking his place on the active roster will be linebacker Joe Mays, who returns after serving a one-game suspension for his Week 3 hit on Texans QB Matt Schaub.
Tight end Virgil Green, who is back working with the team after serving a four-game PED-use suspension, was also reinstated to the active roster.

Second-year safety Quinton Carter was placed on IR and will undergo microfracture surgery next week on the same knee he had arthroscopically repaired during training camp.
With Joe Mays suspended for tomorrow's game against Oakland, two spots had opened on the active roster; Denver promoted safety Duke Ihenacho and linebacker Mike Mohamed to fill them.
The Broncos have re-signed linebacker Mike Mohamed to their practice squad today; Jacksonville had waived him from their PS yesterday, two weeks after having signed him.
To make room for Mohamed, their own 2011 sixth-round pick, Denver waived TE Cornelius Ingram.
With the one-game suspension of Joe Mays and the injury to Nate Irving (concussion), Denver is currently down to five healthy linebackers. Von Miller, Keith Brooking, and Wesley Woodyard are expected to start on Sunday, with sixth-rounder Danny Trevathan and undrafted rookie Stephen Johnson as backups.
Manny Ramirez's days functioning as a turnstile along the Broncos offensive line are nearing an end.
Right guard Chris Kuper has returned to participate in today's padded practice, raising hopes that he will be available on at least a part-time basis on Sunday against Oakland. However, Lindsay Jones says the seventh-year player is unlikely to dress Sunday.
Ramirez is the only of Denver's five starting offensive linemen to receive a negative overall score from PFF (-5.3), although he did grade out at +2.1 for the opening win over Pittsburgh.
ESPN's Chris Mortensen is reporting that the two sides are closing in on an agreement which would bring the real officials back in time for Sunday's games.
Peter King says that if an agreement is reached by tomorrow afternoon, then the regular refs would indeed be available to report for work on Sunday. This is apparently thanks in large part to the work of Ed Hochuli, who has taken the initiative of keeping his colleagues up to snuff on the latest rule changes and testing their knowledge weekly.
According to Adam Schefter, the hit by Broncos linebacker Joe Mays on Matt Schaub during Sunday's loss to the Texans has landed Mays a one-game suspension from the league.
The fifth-year player had earlier been penalized $7,875 for a Week 2 hit on Falcons QB Matt Ryan.
John Fox and Jack Del Rio were, shall we say, quite open with their feelings during the game - enough so, that the Ginger Hammer had one of his lapdogs phone the Georgia Dome at halftime to demand Denver's coaches back off the scabs.
Today comes another admonition, in the form of a $30K fine for Fox, and a $25K penalty on Del Rio.
Our message remains unchanged: GFY, Roger Goodell & Ray Anderson.
The Broncos are placing fourth-round pick center/guard Philip Blake on IR, and promoting center C.J. Davis from the practice squad to take his place on the 53-man roster. Adam Grant, who spent the 2011 season on Denver's practice squad, will rejoin the group in place of Davis.
Blake was inactive for Denver's first two games and was listed on the team's injury report as having a "Thump" issue which limited his practice on Saturday. So, either thump injuries are a big deal, or something else has happened to Blake.
Davis made the team out of training camp but was cut loose to facilitate the addition of veteran center Dan Koppen.
According to Mike Klis, the Broncos worked out three veteran defensive tackles on Tuesday.
Brian Price was a 2010 second-round pick of the Bucs, who traded him to the Bears in July for a seventh-rounder. Price had 24 tackles and three sacks in 15 games (14 starts) for Tampa bay last season. He was cut by Chicago when they signed Amobi Okoye, who himself had left Chicago for Tampa Bay as a free agent in April.

Broncos corner Tracy Porter was named the AFC's Defensive Player of the Week for his season-opening performance against the Steelers.
The fifth-year player was credited with eight tackles (one for loss), five passes defensed, and his late interception of Ben Roethlisberger and subsequent TD return sealed the 31-19 victory for Denver.
