Kirkland, WA (My Sportsbook) - Seattle Seahawks quarterback Matt Hasselbeck is listed as doubtful for Sunday's game against the Bears after suffering a fractured rib last week against San Francisco.

Hasselbeck did not participate in practice this week, and Seneca Wallace will get the start under center if Hasselbeck is unable to go.

The 33-year-old is coming off an injury-riddled season in 2008 in which he played just seven games. In the first two games of 2009, in which the Seahawks are 1-1, Hasselbeck has 376 yards passing and three touchdowns.

Also listed as doubtful is linebacker Lofa Tatupu, who is battling a hamstring injury. Tatupu has played in the first two games of the season, registering five tackles and a sack.

Linebacker LeRoy Hill (groin), offensive tackle Sean Locklear (ankle) and cornerback Josh Wilson (ankle) have all been ruled out of the game. Offensive tackle Walter Jones (knee), cornerback Ken Lucas (groin) and defensive tackle Brandon Mebane (calf) are all questionable.

Wide receiver T.J. Houshmandzadeh, who missed practice Wednesday and is suffering from a back injury, participated fully in practice Thursday and Friday and is listed as probable.
