Seattle Seahawks safety Earl Thomas is doubtful for Thursday against the Arizona Cardinals with a hamstring injury, head coach Pete Carroll confirmed.
Thomas was previously considered a game-time decision.
Bradley McDougald will likely start in Thomas' place.
Thomas missed Sunday's game against the Washington Redskins with the injury. The five-time Pro Bowler suffered the injury while trying to catch Houston Texans receiver DeAndre Hopkins during an Oct. 29 victory.
Through seven games, Thomas has 38 tackles, a forced fumble, and two interceptions.
