Walter Thurmond to play Sunday

RENTON, Wash. -- Seattle Seahawks cornerback Walter Thurmond will be back on the field Sunday after his four-week suspension for a substance-abuse violation, but Byron Maxwell will continue to start.

"Byron has played great football for us," Seattle coach Pete Carroll said Friday. "It's a statement [remaining in the starting spot] about what he's done and how well he has played."

Maxwell replaced Thurmond, who was starting in place of the injured Brandon Browner before Thurmond's suspension. Browner is suspended indefinitely for a substance-abuse violation.

"It feels good to be back," Thurmond said Friday. "I've been training the whole time, but it will be good to get on the field Sunday. I've been studying and keeping up with everything."

Thurmond said his teammates supported him during his suspension.

"I didn't have to explain anything to anybody," Thurmond said. "Everyone understood the situation. We all make mistakes. It's a great group of guys in here, and no one was judgmental about the situation. They were more encouraging than anything.

"Life is about learning from your mistakes. I've gone through a lot of stuff in my life, and I've learned. It was a hiccup in the road, and I'm moving forward from it."

To make room for Thurmond, the Seahawks released cornerback Perrish Cox. Cox, 26, had three tackles in two games with Seattle this season.
