SEATTLE -- Defensive end Patrick Kerney will not return after suffering a groin injury, the Seahawks announced.

Kerney was having some success against Cardinals right tackle Levi Brown, but not in a way that was threatening to affect the outcome.

The ability of Kerney, Walter Jones and Matt Hasselbeck to stay healthy this season was a key variable. All have missed games. Their futures are now measured week to week.
