(Renton, WA)  --  Seattle Seahawks head coach Pete Carroll says it's not known yet whether Marshawn Lynch will be ready for Monday night's game against Detroit.  Lynch has been nursing several injuries, including a hamstring injury that kept him out for most of Sunday's game against Chicago.  Carroll says the team is waiting on results of an MRI to get a better idea of Lynch's progress.  Rookie reserve running back Thomas Rawls spelled Lynch against the Bears, gaining 104 yards on 16 carries.
