Seattle Seahawks star running back Marshawn Lynch is questionable for Sunday's season-opener against the Arizona Cardinals due to a back injury.
Lynch, who signed a multi-year contract extension with the team in the offseason, took limited reps in practice on Thursday and Friday.
In 15 games for Seattle last year, Lynch posted 1,204 yards on 285 carries to go with 12 touchdowns.
Lynch became a fan-favorite in Seattle after he routinely broke huge runs and squeezed out of almost inescapable tackles to lift his team, something he affectionately called "going beast mode."
Tackle James Carpenter (knee), defensive end Greg Scruggs (hamstring) and wide receiver Golden Tate (knee) are all out for Sunday's game.
