The Seattle Seahawks will likely be without both of their starting tackles on Sunday against the Detroit Lions.

Seattle placed right tackle Abraham Lucas on injured reserve Wednesday because of the sore right knee that bothered him in training camp and sidelined him in the second half of the season opener. 

Speaking before the move became official Pete Carroll said both Lucas and left tackle Charles Cross were "hurting" and that it would be a challenge for either to play Sunday.

Cross sprained his right big toe late in the third quarter of Week 1.

The Seahawks signed Jason Peters, 41, to their practice squad Tuesday.

They also added a pair of tackles to their 53-man roster Wednesday, signing Raiqwon O'Neal off the Tampa Bay Buccaneers' practice squad and McClendon Curtis off the Las Vegas Raiders' practice squad.
