RENTON, Wash. – Seattle Seahawks middle linebacker Lofa Tatupu went on the injured reserve list with a torn left pectoral muscle. He had surgery Thursday.

The defensive captain was injured in the first half of Seattle's loss to Arizona on Oct. 18. He was hit high by teammate Deon Grant as both tried to make a tackle.

On Wednesday, six-time All-Pro left tackle Walter Jones went on injured reserve.

Quarterback Matt Hasselbeck practiced after missing two consecutive workout days. The ribs he broke on Sept. 20 at San Francisco still aren't healed, but he and coach Jim Mora said the three-time Pro Bowl passer will start Sunday at Dallas.
