Kampman has 11 sacks, a half-sack shy of the NFL lead and will try to add to that total when he squares off against McQuistan, the Raiders' third-round pick last year who has had to move from guard to right tackle after starter Cornell Green was lost for year due to a season-ending ankle injury.
"It's going to be a heck of a test," Raiders coach Lane Kiffin said Thursday. "(Kampman's) a guy that plays every snap and is extremely powerful. It's going to be a real challenge."
McQuistan started his final 42 games at left tackle while at Weber State but was drafted by Oakland to play guard. He started six games as a rookie before being pressed into action at tackle this season.
McQuistan played in two games earlier in the season when Green was forced out then took over the full-time starter's job when Green landed on injured reserve.
"In his mind he probably wasn't preparing as well as he needed to prepare when he was a backup," Kiffin said of McQuistan. "So he got thrown in there those two games and didn't play very well. Now all of a sudden he's preparing as a starter, which is the way we want all of our guys to prepare all of the time, and now all of a sudden he's playing really well two starts in a row."
* "It looks right now like it'll be Josh until Daunte just comes out and is able to really do everything," Raiders coach Lane Kiffin said. "Then we'll evaluate it at that time."
* McCown started for the Raiders last week against Denver and passed for 141 yards and three touchdowns in Oakland's 34-20 win. He did so despite suffering a dislocated pinky on his left (non-throwing) hand which ruptured the skin and required stitches.
* McCown has taken the majority of reps with Oakland's offense in practice this week as the Raiders prepare for their trip to Green Bay.
* "It doesn't matter to us," Packers cornerback Al Harris said. "We're going to prepare for the Oakland Raiders' offensive scheme so it doesn't matter who's pulling the trigger. Both of those guys are doing a great job."
