Eagles center Jason Kelce is out for the season with a knee injury suffered in Sunday's win over the Ravens.
Kelce was placed on the season-ending injured reserve list and replaced on the roster by center Steve Vallos, who was in training camp with the Eagles and has played in 40 games in his career. He was a seventh-round pick of the Seahawks in 2007 and also played for the Browns in 2010-11.
Kelce started all 18 games of his career. He injured in the third quarter against Baltimore. Dallas Reynolds entered the game for his first career regular-season action and is the likely replacement in the starting lineup going forward.
