ALAMEDA, Calif. (AP) - Oakland defensive tackle Richard Seymour missed his second straight practice Friday, leaving him questionable for Sunday's game in Minnesota.
Seymour has been hampered by a knee injury and has not practiced since Oakland's 24-17 win in San Diego on Nov. 9. Coach Hue Jackson sounded optimistic earlier this week when asked if Seymour would play against the Vikings but backed off that stance slightly on Friday.
"Obviously (he's) not where we want him yet," Jackson said. "I feel good about it but we've still got to see."
If Seymour can't play, it would be a huge setback for Oakland's defense. The Raiders are 25th against the run and have the task of trying to slow down Minnesota running back Adrian Peterson, who is third in the NFC in rushing with 846 yards and has 10 touchdowns.
Two other starters on Oakland's defense are also questionable. Safety Michael Huff (ankle) was downgraded after suffering a setback while rookie cornerback DeMarcus Van Dyke is still recovering from a hamstring injury.
Seymour has been the anchor of the Raiders defensive line since being traded from New England less than two weeks before the 2009 season opener, starting all 38 of the games he's played in for Oakland.
This year, Seymour has 24 tackles and is second on the team with five sacks.
"We'll see where we are," Jackson said. "We still have a couple of days left and we'll go from there."
The news on Huff wasn't as encouraging, though Jackson is hopeful the safety can play against the Vikings. Huff has been in a walking boot but did not have it on as he walked through the Raiders locker room before boarding the team flight to Minnesota.
It isn't much better on offense.
Although center Samson Satele and tight end Kevin Boss are probable, Oakland will be without running back Darren McFadden and wide receiver Jacoby Ford. Both are sidelined with foot injuries and have been ruled out for Sunday's game.
Kicker Sebastian Janikowski is also probable after being slowed by a hamstring injury. He missed the Raiders' 28-0 loss to Kansas City on Oct. 23 and is only 2 of 4 on field goal attempts since coming back.
Before getting hurt, Janikowski was among the NFL's top kickers. He tied a league record with a 63-yard field goal during Oakland's opener in Denver on Sept. 12.
