SEATTLE (AP) Seattle Seahawks starting quarterback Trent Dilfer was knocked out of his team's exhibition opener with what appeared to be a right knee injury Saturday night.

Playing in his third series against the Indianapolis Colts, Dilfer was hit by defensive tackle James Cannida and defensive end Chad Bratzke as he attempted a pass to Koren Robinson with 2:02 gone in the second quarter.

Dilfer was helped off the field and then was taken by a cart to the Seahawks' locker room.

Dilfer, given Seattle's No. 1 quarterback job during the offseason by coach Mike Holmgren, threw a 20-yard touchdown pass to James Williams in the first quarter.

The Seahawks led 10-0 when Dilfer left and was replaced by Matt Hasselbeck.
