Mike Williams started at right guard in Sunday's game against the Carolina Panthers, replacing Chad Rinehart.
For Williams, it was his first NFL regular season game since Nov. 27, 2005, when he was a member of the Buffalo Bills. (That game, incidentally, was also against the Carolina Panthers.)
In the Redskins' first four games this season, Williams was available to play but did not see any action.
Last week, he took all of the right guard reps in practice.
Rinehart had started the last two games at right guard. He was declared inactive for the Panthers game.
It is certainly a step back for Rinehart, a third-round draft choice by the Redskins in 2008.
In the last two games, the Redskins had some success running to the right behind Rinehart and Stephon Heyer, but there were some issues in pass protection.
Williams, listed at 6-7 and 337 pounds, has played tackle most of his career.
He had two starts at left guard during the 2005 season with the Bills, including the game vs. Carolina.
"The transition moving inside is not that difficult," Williams said last Friday. "You have a tighter area of responsibility, as opposed to tackle where a defensive end can go around you and you have to follow him all over the field."
Williams was getting tutoring through pre-game.
Randy Thomas and Kedric Golston joined Williams on the field for some extra work about an hour before kickoff. It appeared Thomas was working with Williams on blocking technique. At one point, Williams took some reps against Golston.
Along with Rinehart, the Redskins' list of inactives were as follows: Hunter Smith, Kevin Barnes, Anthony Alridge, Edwin Williams, Robert Henson, Rinehart, Marko Mitchell and Anthony Montgomery.
Smith was replaced by Glenn Pakulak at punter. Pakulak was signed to the roster on Saturday.
Montgomery remained sidelined with knee tendonitis.
-- PEPPERS SHAKES UP REDSKINS
The front page of the Charlotte Observer's sports section on Sunday questioned whether Carolina defensive end Julius Peppers was "worth" his multi-million dollar salary.
From the Redskins' perspective, Peppers was worthy of plenty of attention.
Peppers was active against the Redskins, recording four tackles, two sacks and a safety.
Peppers matched up against Stephon Heyer most of the game. On the safety, he fended off Heyer's block and burst into the backfield to take down Clinton Portis.
The Redskins had to give Heyer and D'Anthony Batiste, in the game when Chris Samuels suffered a stinger, some tight end help with Chris Cooley and Fred Davis.
Cooley was held without a catch in the game. His streak of consecutive games with a reception at 76 came to an end.
-- QB RATING VS. REDSKINS
The Redskins' defense continued its NFL-best streak of not allowing an opposing quarterback to reach a QB rating of 100 or more.
By holding Jake Delhomme to an 82.3 rating, the defense improved its streak to 26 games. (The stat is based on a minimum of 20 pass attempts.)
The Atlanta Falcons are next on the list with 10 consecutive games. Indianapolis Colts was at nine heading into Sunday's action.
Dallas Cowboys quarterback Tony Romo was the last QB to post a 100 passer rating against the Redskins. He accomplished it on Nov. 18, 2007, in a 28-23 win over the Redskins at Texas Stadium.
-- WHERE'S LEWIS?
New offensive consultant Sherman Lewis watched Sunday's game from the coach's box.
Lewis, hired by the team last Tuesday, is expected to add another viewpoint to the Redskins' struggling offense.
In comments last week, Jason Campbell seemed unfazed by the hiring.
"I can remember being in college and we had a consultant who came along," Campbell said. "It's not like he is taking over the offensive coordinator position or calling plays. He sits in meetings with the coaching staff and he gives you new ideas. It's nothing serious to me."
