Hasselbeck listed as doubtful with recurrent back pain
Both missed practice Friday. Both were expected to be listed as doubtful on the injury report.
Seneca Wallace took all of the first-team snaps in practice after Hasselbeck's lingering back issues flared up, preventing him from practicing.
Hasselbeck missed five games this season because of a bulging disk, which was pressing on a nerve and causing "dead leg."
"Not as severe," Holmgren said, when asked if Hasselbeck's current situation was the same as before, according to the Seattle Times. "But it's some of the same symptoms, yes."
A knee injury prevented Jones from practicing all week.
The Seahawks also placed starting left guard Mike Wahle on injured reserve Friday. Starting center Chris Spencer and Rob Sims, who opened the season as the starter at right guard, are already on injured reserve.
Hasselbeck absorbed seven sacks during a 34-9 defeat to the Dallas Cowboys on Thanksgiving. He finished the game but experienced back trouble this week.
