The Seahawks will get some reinforcements back for Thursday night's game at San Francisco, including All-Pro middle linebacker Bobby Wagner, who missed last week's game with a pectoral injury.
Also expected back from injuries are defensive end Frank Clark (hamstring) and Tye Smith (hip flexor).
"We were fortunate in these couple of days that some guys were able to return," Seahawks coach Pete Carroll said. "That's good news for us."
In the case of Wagner, the Seahawks held him back last week despite the linebacker pushing to play, and Carroll said they wouldn't risk bringing Wagner back if they thought the injury could be made worse by him playing.
"We wouldn't be playing him if we thought that," Carroll said. "You never know, but he feels really good and he's ready to go. It's great to have him back, and if he has any issues at all, then we know how we'll go like we did last week."
Cornerback Richard Sherman, who was held out of the previous two days of practice, was back on the field Wednesday and is also expected to play.
"He's ready to go," Carroll said. "He went today. We just had to rest him for a couple of days. He had a little thing in his ankle he just had to get a break on."
One starter who will not play is center Patrick Lewis, who injured his ankle against Carolina in his first game as the starter. Drew Nowak, who started Seattle's first five games, will likely get the start, with Lemuel Jeanpierre serving as the backup just two days after re-signing with Seattle.
"Patrick won't make it back yet with a sprained ankle," Carroll said. "We're very fortunate to have Lem come back with us. He knows everything that we're doing and he can jump back in. Drew goes right back into the starting spot. We feel like we're lucky to have Lem out there available to us."
Carroll said linebacker Brock Coyle, who was placed on injured reserve/designated for return Tuesday, had surgery on his injured knee. Receiver Paul Richardson, who is close to being back form a knee injury, was not taken off the physically unable to perform list this week because of the short practice week.
"This is not a week to really test a guy and check him out, because we have to go so light with the tempo in practice," Carroll said.
Defensive tackle Jordan Hill is out again with a quad injury, but is close to being back.
"He'll have a great chance to be ready to go next week," Carroll said.
Cornerback Marcus Burley, who had surgery to repair a broken thumb earlier this month, won't play Thursday, but did return to practice Tuesday and Wednesday.
"He has practiced both days," Carroll said. "We're going to give him one more weekend of break, but he could run around and do everything. He's in a cast. It's a fantastic turnaround for him. He would like to play, but we're going to give him another week."
Not on the injury report and expected to play is running back Fred Jackson, who was uninjured in a one-car accident outside of the VMAC Wednesday evening.
"Fred lost control of his car, had an accident, and he was ticketed for that," Carroll said. "… We're very fortunate that nobody was hurt. We're lucky in that regard.
"We talked about it today with the whole group. Fred talked to the team as well just to give everybody the heads up so we make sure we're doing the right thing and not making any more mistakes… He told what happened so they all knew for the heads up for everybody else to keep your eye on the road and do things right and drive carefully and protect the people around you and ourselves."
Fullback Derrick Coleman, however, will not play because of a concussion which was the result of a car accident last week.
"He still is out," Carroll said. "He will not play this week."
