Seahawks coach Pete Carroll said Friday that running back Marshawn Lynch is dealing with a calf injury and will be a game-time decision in Sunday's game against the Bears, according to NFL Network.

Lynch, who missed practice Wednesday and Friday, is off to a slow start this season with just 114 yards on 33 carries through the first two weeks, and no touchdowns.
If Lynch is unable to play, 34-year-old Fred Jackson will start in his place. Jackson only has 13 yards on three carries so far this season, but did catch a 5-yard touchdown against the Packers last week.
