Richie Incognito's return from suspension should give the Raiders offensive line a lift Sunday at Minnesota.
That only holds true if the front otherwise remains intact. That's uncertain at this stage, with the right side dealing with injury issues.
Star right tackle Trent Brown has dealt with a knee injury all week, and right guard Denzelle Good popped up on the injury report Friday after hurting his ankle in individual drills.
Both guys are considered questionable against the Vikings on the Raiders' official injury report.
Brown's status has been monitored all week, after he couldn't finish the previous game against Kansas City. He didn't work Wednesday or Thursday but was a full participant Friday, in more of a walk-through style practice.
"He's still sore, but he looked good today," head coach Jon Gruden said. "He's a tough guy. Hopefully, he can be ready to go Sunday."
The Raiders would start either Brandon Parker or David Sharpe if Brown can't play. Neither option is attractive. Parker struggled in Brown's place last game.
Jordan Devey's the likely right guard if Good can't go. Losing either member of the line's right side would impact the run game, which had been strong going in that direction.
The Raiders have problems elsewhere, with slot cornerback Lamarcus Joyner questionable with a groin problem.
Gruden also said that Corey Liuget likely will make his Raiders debut Sunday, especially with P.J. Hall battling an illness that is sweeping through the Raiders' complex.
Receiver Tyrell Williams got it last week, and it kept Keisean Nixon on Thursday. Running back Josh Jacobs also is sick, and posted on Instagram he has lost 10 pounds in recent days while sick.
Williams and Jacobs dealt with hip and groin issues, respectively, this week, but the team's top skill players have been taken off the injury report.
