Seahawks coach Pete Carroll said Monday that he's "unsure" whether Marshawn Lynch (back) will play in Week 8 against the Bengals. Carroll said Lynch is "determined to play," but the Seahawks won't know enough until later in the week. Carroll also revealed that TE Zach Miller (concussion) has yet to gain clearance for practice. Tarvaris Jackson's (pectoral) status is also unknown. The Bengals currently rank first in the NFL in defense.
