Athletic director Jim Sterk announced Wednesday that WSU will play all six of its home games on campus at Martin Stadium this coming season.
The Cougars will resume their annual game in Seattle on Sept. 10, 2011, against UNLV.
Washington State has played one game in Seattle each season since 2002. The contract ended after last season's game against Hawaii.
Sterk said Washington State needs to draw about 50,000 for a Seattle game to make it worth moving the game away from Pullman.
