The Redskins made six roster moves on Tuesday, signing two players to the active roster and placing two veterans on Injured Reserve among the transactions.
The Washington Redskins announced on Tuesday that they have signed center John Sullivan and offensive lineman Vinston Painter to the active roster.

In corresponding moves, safety DeAngelo Hall and center Kory Lichtensteiger have been placed on Injured Reserve.
Cornerback Tye Smith was signed to the practice squad as well while linebacker Amarlo Herrera was released from the practice squad.
Sullivan, 31, is a nine-year veteran who spent his entire NFL career with the Minnesota Vikings prior to his signing with the Redskins.
During his time in Minnesota, Sullivan appeared in 109 regular season games with 93 starts, fourth most in Vikings franchise history.
The 2008 sixth-round pick out of Notre Dame is now the oldest offensive lineman on the active roster, one year older than tackle Ty Nsekhe.
Along with Sullivan, the Redskins also have Spencer Long who can play the center position, as he did so in replacement of Lichtensteiger in the second half of Sunday's 29-27 victory over the New York Giants.
Painter, meanwhile, is being signed to the active roster after spending the first three weeks of the season on the Redskins' practice squad.
Redskins head coach Jay Gruden confirmed that Hall had suffered a torn ACL during his press conference on Monday and would miss the rest of the season.
It is a crushing blow for the 13-year veteran, as he was also placed on Injured Reserve during the 2014 season with a torn Achilles.
Gruden said that losing someone as tenured as Hall will hurt for a defensive unit with a lot of new and young faces.
"He's a captain, you know? He's coming along, playing a lot better and better at safety, so it's pretty significant," Grudens said. "Now [Will] Blackmon will take over at that position and we'll go from there. Will played well when he came in. From a player perspective, Will's right there with him, but from a leadership standpoint, D-Hall has done a lot for this organization, a lot for this team. He's going to be missed."
As for Hall's future in football, Gruden said "we'll have to see."
"I think he's got to really take a look at it and see where he is once he does the rehab if he wants to try it again," Gruden said. "I haven't talked to him about that – his future or anything – we just want him to get well first. We want him to have the surgery and make sure he recovers. That's the No. 1 priority right now. After that we'll wait and see."
Lichtensteiger started the first five regular season games for the Redskins last season before being placed on Injured Reserve on Nov. 10 with a designation to return. Josh LeRibeus took over center duties in his place before Lichtensteiger was activated on Jan. 5.
He played in all 72 snaps in a Wild Card Round game against the Green Bay Packers before being the team's starting center once again this season.
