WSU Football vs. Oregon game Sept. 20th is SOLD OUT! Stay tuned ► possible standing-room only sale to come #GoCougs— WSU Cougar Tickets (@WSUCougarTix) September 3, 2014
Washington State has sold out its Sept. 20 game against Oregon, according to the WSU ticket office. As the above tweet notes, some standing-room tickets may become available. Tickets are still available on the secondary market, of course, and I'm seeing individual tickets available for about $70, more than any other WSU home game except for the Apple Cup.
