ALAMEDA -- Center Stefen Wisniewski returned to practice Wednesday, an encouraging development with the Raiders preparing to face a Pittsburgh Steelers team which has a confusing array of blitzes.
Wisniewski, who missed the last two games with a right knee injury, is considered by line coach Tony Sparano to be very good at offensive calls for getting defenders blocked.
While Wisniewski was back on the field, the Raiders were still without fellow linemen Tony Pashos, Andre Gurode and Menelik Watson.
Pashos, who has a hip flexor injury which was originally called a groin injury, began the media window working with the athletic training staff but went indoors less than 10 minutes into the session.
As it stands, the Raiders midweek offensive line consists of Khalif Barnes at left tackle, Lucas Nix at left guard, Wisniewski at center, Mike Brisiel at right guard and Matt McCants at right tackle.
Safety Tyvon Branch, out with a reported fractured ankle since Week 2, was spotted walking without crutches during the bye week but is still not practicing. Linebacker Miles Burris (knee) remains on the physically unable to perform list, while left tackle Jared Veldheer (torn triceps) has not begun practicing after rehabbing from surgery.
