ALAMEDA — 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 ever in an NFL game in the 24-7 loss to the Chiefs.
Coach Dennis Allen said it's too soon to know whether center Stefen Wisniewski, right tackle Tony Pashos or guard/center Andre Gurode will be healthy enough to play Sunday against Pittsburgh.
"I'm hopeful we'll have more guys back, but I won't know until Wednesday," Allen said.
Wisniewski has missed the past two games with an injured knee and his absence has been notable because of his role making the line calls and organizing the line.
He was working on the side Monday with a trainer instead of with the team during the open portion of practice.
Gurode, a former Pro Bowl center, filled in admirably when he had to move from left guard to center, but then he left in the first half against the Chiefs with an injured quadriceps.
That forced Brisiel to move over to center for the first time since he played in NFL Europe in 2007 and put former practice squader Mady at right guard.
Pashos was knocked out of the Chiefs game with a hip flexor and has also been hampered by a groin injury, giving McCants his first playing time as a pro.
