Unger, Bryant out; Harvin also won't play

RENTON, Wash. -- Seattle center Max Unger and defensive linemen Red Bryant will not play Sunday at Atlanta, Seahawks coach Pete Carroll confirmed after practice Friday. Both suffered concussions against Tampa Bay last weekend.

"We're going to take care of them this week and have them ready for next week," Carroll said. "We have some rotations we've been working on [in Bryant's absence] in practice, but the same guys will be playing for the most part."

Carroll said rookie defensive tackle Jordan Hill also will not play because of a biceps injury.

Lemuel Jeanpierre will get his third start of the season for Unger, who missed two games earlier this season

"He's done really well," Carroll said of Jeanpierre. "Whenever he has played for us he's come through."

Receiver Percy Harvin will not be activated this weekend, but Carroll is pleased with his progress.

"Percy is the best he's been," Carroll said. "He had another good workout [Friday]. He's not ready to play this week, but will return to practice, hopefully, next week. All the signs are really encouraging. He feels good and he's not having any issues after he works out. We're hoping he'll be able to jump back into it next week."

Starting right tackle Breno Giacomini, who returned to practice this week, is officially listed as doubtful for Sunday; he will not start and isn't likely to play. Giacomini and left tackle Russell Okung could return against Minnesota next week.

"They practiced and were able to handle the work, so that's a really good sign," Carroll said. "Those guys are dying to play. We will go into next week to see if they can handle it [at practice] and get ready to play."

Fullback Derrick Coleman continued to rehab a hamstring injury and is out for Sunday. Backup safety Jeron Johnson is listed as questionable with a hamstring injury.
