ST. LOUIS -- Arizona Cardinals linebacker Reggie Walker was sidelined by a blow to the head in the first half and the team said his return was questionable.

It wasn't immediately clear when Walker, the backup behind Daryl Washington at an inside linebacker spot, was hurt against the Rams on Thursday night. The injury was announced in the second quarter.

Walker has played in all four games as a reserve and on special teams.
