PITTSBURGH -- Defensive end Nick Eason has signed a one-year extension with the Pittsburgh Steelers.
Eason signed with Pittsburgh as an unrestricted free agent in 2007.
Kirschke, 35, has not re-signed after spending six seasons with Pittsburgh -- he has played in the NFL since 1997 -- and is expected to retire. He did not miss a regular-season game with the Steelers due to injury until last season.
