Because of the injury situation at outside linebacker, the Steelers signed Justin Kurpeikis to their practice squad. Kurpeikis, a former Penn State star, was with the Steelers' roster in 2001-02.
Rookie wide receiver/kick return specialist Willie Reid was downgraded from doubtful to out. Already ruled out of the Oakland game are outside linebacker James Harrison (ankle) and safety Mike Logan (hamstring).
Running back Duce Staley missed practice for personal reasons.
The Steelers are flying to California Friday. They are flying into San Jose. They will have a walkthrough at McAfee Coliseum Saturday, then fly back to Pittsburgh after the game Sunday from Oakland.
