Illinois will play Washington at Soldier Field in Chicago on Sept. 14, 2013. The game originally was to be played in Champaign.
Athletic director Mike Thomas has said he wants to play a game in Chicago in the years Illinois doesn't play at Northwestern.
"This is a great opportunity for our football team to play in one of the most historic football venues in the nation," Thomas said. "Soldier Field is in an incredible location that will allow our fans in the Chicagoland area and from around the state an opportunity to watch the Fighting Illini take on an outstanding Pac-12 opponent in Washington."
Illinois is to play at Washington in 2014.
The 2013 schedule is complete and features seven games at Memorial Stadium. The last slot was filled by Miami (Ohio), which visits Sept. 28. Illinois will have open dates on Sept. 21 and Oct. 12.
In 1994, Illinois lost to Washington State 10-9 at a half-filled Soldier Field.
