RENTON, Wash. (AP) —Seahawks center Chris Spencer is out at least a month for a torn thigh muscle.
Coach Jim Mora told Seattle radio station KJR on Monday morning that Spencer tore the quadriceps muscle in his left leg and will 'absolutely' miss at least the first two regular season games.
Spencer was taken off the field by a motorized cart in the second quarter of Saturday night's preseason win over Denver.
Steve Vallos and rookie second-round draft choice Max Unger are expected to get the first shots to replace him.
Seattle is already without nine-time Pro Bowl left tackle Walter Jones. The 35-year-old had his second knee surgery in eight months last week.
Starting left guard Mike Wahle was released at the start of training camp. The two-time Pro Bowler failed a physical after shoulder surgery.
