Kick and punt returner Bryan Walters will not play Sunday because of a concussion, one of seven Seattle Seahawks on the active roster who are out for the game in Charlotte against the Carolina Panthers.

Seahawks coach Pete Carroll said Friday that receivers Doug Baldwin and rookie Paul Richardson would handle the return duties this weekend.

Carroll said Baldwin wants to do both, "but he's going to do one of them." Carroll didn't say which one, but look for Baldwin to return kickoffs and Richardson to get a shot at returning punts. Richardson and cornerback Richard Sherman have been practicing punt returns all season.

Starting corner Byron Maxwell (calf strain) and starting center Max Unger (foot injury) are still are out this weekend, but Carroll hopes both will return to practice next week.

Second-year player Tharold Simon will get his second NFL start and cornerback, replacing Maxwell. Simon sprained his ankle in his first NFL start last week at St. Louis and left the game, but he practiced all this week and is ready to go.

Also out for Sunday are starting tight end Zach Miller, starting middle linebacker Bobby Wagner (turf toe), backup defensive tackle Jordan Hill (sprained ankle) and fullback Derrick Coleman, who has surgery Wednesday on his broken foot.

Running back Robert Turbin will handle the fullback duties again Sunday. Backup tight end Luke Willson will return after missing the St. Louis loss with a groin injury.
