GLENDALE, Ariz. -- Seattle Seahawks cornerback Richard Sherman will miss the rest of the season after suffering a ruptured Achilles in Thursday night's 22-16 win over the Arizona Cardinals.

Sherman exited the game in the third quarter and did not return. He said he expects to undergo surgery after swelling in the Achilles goes down in the next few days.

"No coming back from that until you get surgery," head coach Pete Carroll said, adding that Sherman "couldn't even walk" after leaving the game and standing on the sideline.

"He's been a bastion of consistency, competitiveness and toughness. We're going to miss the heck out of him."

Sherman said his Achilles has actually been bothering him all season and that he has tried to avoid making any drastic cuts. On the play in which he was hurt, Sherman said the defense was playing Cover 2 and that he was going for an interception.
