If it’s Wednesday …

RENTON, Wash. – This season, Wednesday has become quarterback Matt Hasselbeck’s routine day for rest. And he has almost as many aches as weeks in the season.

The battered 34-year-old, three-time Pro Bowl passer sat out another practice with a sore throwing shoulder, but coach Jim Mora said Hasselbeck is probable to start for the Seahawks on Sunday at Houston.

“He’s just sore,” Mora said, before backup Seneca Wallace ran the offense through practice. “Nothing structurally wrong, and he should be back out there (Thursday).”

Mora called Hasselbeck’s soreness a product of “wear and tear.”

There’s been plenty of both this season.

Sunday, Hasselbeck was hit by San Francisco’s Dashon Goldson at the end of a third-down scramble in the third quarter. The quarterback was on his back for a tense moment with a doctor and trainer over him. Yet he finished Seattle’s win and was 12-for-13 passing after the injury.

“I just needed a minute,” he said.

It was the second time this season Hasselbeck got hurt trying to run against the 49ers. Patrick Willis broke the quarterback’s ribs on his dive for the goal line on Sept. 20.

He missed two games then he banged his throwing shoulder while making a tackle on an interception early in a game against Detroit on Nov. 8.

That shoulder was just getting better when he hurt it again Sunday.
