OAKLAND, Calif. (AP) -Both the Raiders and Philadelphia Eagles lost key players midway through the first quarter of their game Sunday.

Eagles left tackle Jason Peters limped to the sideline with assistance at the 7:20 mark after he blocked Oakland defensive tackle Tommy Kelly and another player rolled up his leg.

He was taken to the locker room for observation on his left knee and was replaced by King Dunlap.

Raiders cornerback Nnamdi Asomugha was lying down on a table behind the bench being examined by several members of the medical staff.
