The team went into halftime Sunday without Thurmond, who rode to the locker room on a cart after colliding with teammate Earl Thomas while defending a Cleveland Browns deep pass late in the second quarter.
Team doctors appeared to be looking at Thurmond's left leg. Thurmond suffered a career-threatening injury to his right knee at the University of Oregon. I'll update this item with additional details when I have them.
Rookie Richard Sherman moves up the depth chart with Thurmond out. Seattle trails 3-0 at halftime against the Browns.
Update: Ankle injury for Thurmond. Return is doubtful. That is from the team.
