Jackson, who played for the Raiders from 1997-2001, has been a solid run defender for four teams during his 10-year NFL career. At 360-plus pounds, the former Raider would appear to be a good fit for an Oakland defense ranked 29th against the run at 141.7 yards a game.
The Raiders could also use help because of Gerard Warren's lingering thigh injury. Warren did not practice Wednesday, has not practiced since the bye week and is a question mark to play this week against Tennessee.
"It's disappointing," Kiffin said. "He still is not out here. We would have thought by now he would have been back from the injury that happened during the bye week but he's not. Hopefully he'll be out here tomorrow.
But Kiffin said on Wednesday that Oakland has no intentions of bringing Jackson in for a workout.
"You always look at everything," Kiffin said, "but as of right now we wouldn't make a move, just because of where our roster's at right now."
Last week against the Chiefs, the Raiders played better against the run but still gave up more than 125 yards on the ground for the third straight game and fourth time in six games overall. Oakland used a variety of combinations inside against Kansas City -- Terdell Sands and Warren Sapp, Sands and Tyler Brayton, Brayton and Tommy Kelly, Kelly and Sapp, Sands and Kelly -- in an effort to keep the players fresher.
They might have to use the same plan against Tennessee, which enters the game with the fifth-ranked running offense using a combination of LenDale White and Chris Brown.
"LenDale gets better with carries," Kiffin said. "He was always a guy at ‘SC that had big second halves. A powerful guy that wears you down eventually."
