Linebacker Rocky McIntosh left Sunday night's game against the Giants with a knee injury. He did not return.
The severity of the injury remains uncertain.
The Redskins will update McIntosh's status on Monday after he undergoes an MRI to further evaluate the injury.
McIntosh, in his second NFL season with the Redskins, was replaced by rookie H.B. Blades on running downs and Khary Campbell on passing downs.
McIntosh suffered the injury on the Redskins' second defensive series.
He was aided by athletic trainers on the Giants Stadium turf for several minutes, but he was able to walk off the field.
-- KEEPING THE TEAM TOGETHER
How have the Redskins been able to stay close as a team despite a series of tough losses, crushing injuries and the Sean Taylor tragedy?
Gregg Williams points to one man.
"It is Joe Gibbs," Williams said. "No doubt about it."
Added Williams: "There couldn't be a better person in that respect in how he addresses the team each and every day. He cares about the team every day and he has brought those kinds of people in here.
"The character of the team is strong, but it comes from Joe."
-- THOMAS TRAVELS
Randy Thomas, placed on injured reserve last week due to triceps and elbow injuries, was on the Redskins' sidelines for Sunday night's game.
Thomas has served as an emotional leader on the sidelines all season long this year. Since he was sidelined Week 2 with the triceps injury, he has traveled with the team on road trips.
Thomas tried to return last week against Chicago, starting the game and playing a quarter. He could not finish the game after injuring his elbow.
Thomas's return inspired his teammates, but now he will have to inspire from the sidelines.
-- IN A CORNER
John Eubanks, another first-year cornerback, was inactive for Sunday's game. Eubanks suffered a toe infection last week.
With Eubanks out, veteran corner David Macklin saw action in nickel and dime packages for the Redskins.
The Redskins' complete list of inactive players was as follows: Jason Campbell, wide receiver Anthony Mix, Eubanks, tight end Brian Kozlowski, linebacker Randall Godfrey, offensive lineman Mike Pucillo and defensive tackle Ryan Boschetti.
James Thrash's return from an ankle injury sidelined Mix, who spent time on the Giants' active roster and practice squad earlier this season before signing with the Redskins.
-- JASON CAMPBELL AMONG INACTIVES
As expected, quarterback Jason Campbell was among the Redskins' inactives for Sunday's game against the New York Giants.
Campbell missed his first game since he took over the Redskins' starting quarterback job in Week 11 of the 2006 season. He did not travel with the team to North Jersey.
On Sunday night, Todd Collins started for the Redskins at quarterback and he was backed up by Mark Brunell. Sam Hollenbach, signed by the club last Friday, was listed as the third quarterback.
-- TORRENCE DRAWS FIRST START
The Redskins' defense opened with a unique package that included three cornerbacks and three safeties.
As a result, cornerback Leigh Torrence earned his first NFL start. The first-year player has seen extensive action due to the midseason injury to Carlos Rogers.
Heading into the Giants game, Torrence had logged 19 tackles (12 solo) on the season. He also had 11 special teams tackles.
-- TRAGEDY FOR GIANTS' TYREE
The New York Giants' list of inactive players Sunday night included wide receiver David Tyree, whose mother Thelma died Saturday night after suffering a heart attack in Florida.
Tyree is a 5-year veteran and a 2005 Pro Bowler who has played in 11 games this season. He has two receptions and is tied for second on the team with eight special teams tackles.
New York's inactive list also included safeties Gibril Wilson and James Butler. The Giants will start a pair of rookie defensive backs in Craig Dahl and Michael Johnson.
