RENTON, Wash. —The Seahawks are expecting backup Seneca Wallace to start at quarterback for Matt Hasselbeck on Sunday against Chicago.
Coach Jim Mora said after practice Friday that Hasselbeck's broken rib makes him "extremely unlikely" to play against the Bears.
Hasselbeck, who turned 34 on Friday, did not practice all week. The three-time Pro Bowl passer fractured a rib last weekend when he got hit by San Francisco's Patrick Willis on a dive for the goal line.
Mora also says it's unlikely Lofa Tatupu will play. The three-time Pro Bowl middle linebacker has a hamstring injury.
Walter Jones will be a game-time decision. The nine-time Pro Bowl left tackle practiced fully for the third consecutive day. He had his second knee surgery in nine months in August.
