Reed was signed by Cleveland as an undrafted rookie out of Florida State; Weems was an undrafted signee by the Vikings out of Oregon, and he was on Indy's practice squad for the first two weeks of this season.
The Broncos had two open spots on the practice unit following last weekend's promotion of Mohamed and Duke Ihenacho to the 53-man roster. G Adam Grant was waived from the practice squad to create the third open spot for today's additions.
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.
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.

As expected, the Broncos have signed center Dan Koppen and brought back quarterback Caleb Hanie.
To make room for them, the team placed DT Ty Warren on IR and waived guard/center C.J. Davis. Denver also cut lineman Wayne Tribue from the practice squad.
Taking the place of Tribue on the practice squad will be DE Jamie Blatnick, who was among the team's final cuts this year after collecting seven tackles in the preseason (five solo).

Five and a half months after getting outbid for the services of center Jeff Saturday, the Broncos have agreed to terms with former longtime Patriots center Dan Koppen.
Like legendary Denver center Tom Nalen, Koppen was drafted out of Boston College, and he started 120 of the 121 games he played for New England from 2003 to 2011.
Denver's season-opening 31-19 over Pittsburgh came with a heavy price, as defensive tackle Ty Warren tore the same triceps that had cost him the 2011 season; he is likely done for the year.
Warren departed during the second quarter of Sunday night's game; it was his first regular-season action since the 2009 season. The former Patriots star had agreed to a reduced $1.5M salary (down from $4M) after a brief holdout over the summer.
John Fox also confirmed the team will re-sign QB Caleb Hanie, who had been released over the weekend in order to keep Denver from having to guarantee Hanie's salary as a vested veteran.
