The Oakland Raiders returned from their bye week facing many of the same questions on the offensive line that they had when they left town last week.

The Raiders began practice Monday with the same makeshift line that struggled mightily in their last game eight days ago in Kansas City with many of their starters still dealing with injuries.

Backups Lamar Mady and Matt McCants are once again working with the first team for the Raiders (2-4) and right guard Mike Brisiel was back at center after playing there for the first time in an NFL game in the 24-7 loss to the Chiefs.

Coach Dennis Allen says it's too soon to know whether center Stefen Wisniewski, tackle Tony Pashos or guard/center Andre Gurode will be back Sunday against Pittsburgh.
