The Redskins have added two more offensive linemen to the active roster with multiple injuries to that group while placing Mason Foster on Injured Reserve and waiving Mack Brown.

The Washington Redskins announced on Saturday that they have signed offensive lineman Orlando Franklin and guard Arie Kouandjio.

In corresponding moves, the team has placed linebacker Mason Foster on Injured Reserve and waived running back Mack Brown.

Franklin, 29, is in his seventh NFL season as he's started all 89 of his regular season appearances between the Denver Broncos and the then-San Diego Chargers.

Drafted in the second round of the 2011 NFL Draft out of the University of Miami, Franklin started all 32 of the  Broncos' regular season games from 2011-12.

In 2015, the Kingston, Jamaica, native started 15 regular season games along with all three of Denver's postseason contests including Super Bowl XLVIII.

In total, Franklin spent four seasons with the Broncos before signing with the Chargers in 2015. He would start 26 games with the Chargers over the course of two years.

He briefly spent time on the New Orleans Saints' roster during training camp this year before being released.

Kouandjio, meanwhile, returns to the Redskins after being signed to the active roster off the Baltimore Ravens' practice squad.

The University of Alabama product, of course, was selected by the Redskins in the 2015 NFL Draft. He's appeared in eight regular season games in his career with two starts.

Their signings comes at a time when Washington's offensive line is battered by injuries. Spencer Long and Ty Nsekhe have already been ruled out for Sunday's game against the Dallas Cowboys, while Trent Williams, Morgan Moses, Brandon Scherff and Tyler Catalina are questionable.

Franklin and Kouandjio join Tony Bergstrom as offensive line signings by the Redskins this week.

Foster has been playing through a torn labrum he suffered in Washington's Week 2 victory over the Los Angeles Rams, a game the linebacker would seal with a late interception of Jared Goff.

The team's starting Mike linebacker had been fighting through the pain, appearing in the last three games for the Redskins to record 16 tackles with a half-sack during that span.

He was limited during Thursday's practice session, but ultimately the pain was too much for Foster to handle.

"He's been trying to play with it, and hats off to him for fighting through the injury," said Redskins head coach Jay Gruden. "There's certain, I guess, categories of what he has right now and his is pretty painful. He can't sleep at night. He wants to get it fixed and I don't blame him. He fought through a couple games for us and I think just the pain has been unbearable for him. His range of motion isn't there and he wants to get it fixed."

As it stands now, the University of Washington product appeared in five games this season to record 31 tackles with a half-sack and an interception.

The Redskins will move forward with Will Compton, Martrell Spaight and Josh Harvey-Clemons taking Foster's reps opposite Pro Bowler Zach Brown.

Compton is in his fourth active season with the Redskins after originally joining the team as a college free agent signing in 2013.

After spending the majority of the 2014 season as a backup, Compton appeared in all 16 regular season games with 10 starts in 2015, recording 96 tackles. Last season, the University of Nebraska product recorded a career-high 106 tackles.

While Compton isn't sure how he'll be utilized moving forward, the news of Foster's injury was difficult on him.

"Mason is one of my boys and it's tough to see him go," Compton said. "I know he's been battling through a lot, but he's got to do what's best for him and I hope he sticks around."

Spaight, meanwhile, is in his third season out of Arkansas. After missing the final 15 games of his rookie season, the 24-year-old returned healthy last year to record 28 tackles in 14 games. Through six games this season, Spaight has recorded 19 tackles.

As for Brown, he appeared in three games this season recording eight carries for 29 yards.
