The Oakland Raiders will be without standout long snapper Jon Condo for the rest of the season after placing him on injured reserve.

The Raiders signed long snapper Thomas Gafford to replace Condo, who injured his shoulder in the fourth quarter Sunday while recovering a muffed punt deep in Denver Broncos territory to set up the deciding points in Oakland's 15-12 upset win.

Condo's injury was the reason behind Oakland's decision to go for two points after scoring a touchdown instead of going for the PAT, which would have given the Raiders a four-point lead. Oakland missed the two-point attempt. Condo did come back to finish the game.

Condo has played in every game for Oakland since the start of the 2007 season. Condo, 34, is signed through next season and has played 141 straight games for Oakland..

Gafford, 32, snapped for the first 11 games of the year for the Chicago Bears before being cut. He was with the Kansas City Chiefs for the six previous seasons and is known for being a capable snapper.
