RENTON, Wash. (AP) -- Seattle Seahawks quarterback Tarvaris Jackson has a "high-grade" strained pectoral muscle in his right chest and will be rested during the Seahawks bye week.
Coach Pete Carroll said Monday that Jackson had an MRI that "showed some stuff" in the pectoral area and there is no time frame for how long Jackson might be out.
Jackson was injured in Sunday's 36-25 win over the New York Giants. He leads a list of significant injuries for the Seahawks that includes Pro Bowl tight end Zach Miller (neck), running back Marshawn Lynch (ankle) and linebacker Leroy Hill (hamstring).
Seattle won in New York without starting wide receiver Mike Williams (concussion) and cornerback Marcus Trufant (back).
