Injuries continued to mount for the Redskins on Sunday night.

Chris Samuels suffered a triceps injury in the fourth quarter of Sunday's game against the Baltimore Ravens.

He was not able to return to the game.

If there's a tear in the triceps, then Samuels could miss significant time. He was scheduled for an MRI on Monday.

The Redskins deactivated Jason Fabini and Chad Rinehart prior to the game, so to replace Samuels, coaches initially turned to Justin Geisinger, a third-year offensive lineman who has seen limited action this season.

Stephon Heyer was already in the game in place of Jon Jansen, who suffered a sprained left knee in the first half.

Later in the quarter, Heyer and Geisinger switched sides. Heyer backs up at both tackle spots, although he is regarded as a natural left tackle.

On defense, Chris Horton suffered a shoulder stinger in the first half and did not return to the game.

Horton was replaced by Mike Green, who finished the game with six tackles.

Clinton Portis also left the game midway through the third quarter. Portis has been slowed by a myriad of bumps and bruises, including knee and neck injuries.

Portis had 11 carries for 32 yards and also caught three passes for 14 yards. He was replaced by Ladell Betts in the lineup for the rest of the game.

The Redskins will update the status of injured players on Monday.
