"The fact Tarvaris Jackson was able to throw on back-to-back days at practice is a sign his strained pectoral muscle is healing.

The fact Jackson has not been able to do that until this week — a month and a half after he suffered the injury — is a sign of just how hurt that muscle was.

On Friday, Jackson was a somewhat surprising participant in all of Seattle's practice, breaking the routine of the previous two weeks in which he was generally limited to handoffs in practice the day after he threw.

"He felt a little bit better, so he got full-go," coach Pete Carroll said after Friday's practice. "That's good news. That's the first time he's been able to do this in weeks."

Seattle receiver Sidney Rice returned to practice Friday after sitting out the previous two days with a sore knee. Rice is listed as probable on Seattle's injury report, which means he's virtually certain to be available for normal duty Sunday. Same for Ben Obomanu, who was limited by a sore knee and ankle earlier in the week.

Safety Atari Bigby and defensive lineman Anthony Hargrove are expected back after missing last week's game, each because of a hamstring injury. The only one of Seattle's starters who is questionable is nose tackle Alan Branch. He did not practice this week and will be a game-time decision because of an ankle injury. Same for rookie cornerback Byron Maxwell, who missed practice with a sore ankle."
