Lock (elbow) is inactive but serving as the Seahawks' emergency third quarterback for Sunday night's contest against the Chiefs, Curtis Crabtree of Fox 13 Seattle reports.
Lock was limited at practice throughout the entire week with a right elbow injury, and he will now likely have the opportunity to have a night off Sunday. Lock will only be eligible to enter the game if both starter Sam Darnold and primary backup Jalen Milroe are unable to continue.
