RENTON, Wash. (AP) Marcus Trufant will make his season debut for the Seahawks on Sunday at Dallas.

Seattle activated the 2007 Pro Bowl cornerback from the physically-unable-to-perform list Friday. Last week was the first time Trufant had practiced since July, when a disk issue in his back began.

Coach Jim Mora expects Trufant to play mainly in nickel defensive alignments on passing downs against the Cowboys. Josh Wilson and Ken Lucas will again be the starting cornerbacks.

Trufant takes the roster place of Lofa Tatupu. The three-time Pro Bowl linebacker went on injured reserve following surgery this week to repair a torn left pectoral muscle.

Seattle will also get starting outside linebacker Leroy Hill back Sunday.
