Stoops is upset about a conference policy requiring only Pac-10 officials to work home games involving league teams in Pac-10 stadiums.
Oklahoma is scheduled to play Washington in Seattle in 2008, but that could change if Stoops and athletic director Joe Castiglione remain dissatisfied with the Pac-10's handling of officiating rules, The Oklahoman reported.
The Sooners were involved in controversial officiating in their last two trips West against Pac-10 foes, including Saturday's game at Oregon, which featured two errors resulting in the suspension of an entire crew and the replay official.
Both mistakes were confirmed by the Pac-10 office. One -- the improper awarding of an onside kick to Oregon -- led to the game-winning touchdown in the Ducks' 34-33 win.
