Arizona State and Oklahoma State are set to play a home-and-home series nearly 30 years after the Sun Devils and Cowboys last played.
ASU will travel to Stillwater for a game Sept. 10, 2022, and the Cowboys will return the favor a year later with a game in Tempe.
Barring bowl or playoff matchups between now and then, the contests will be the fourth and fifth between the schools.
Oklahoma State thrashed ASU 45-3 in Sun Devil Stadium on 1984 before dropping the next two games between the schools.
ASU won 30-3 in Stillwater in 1991 and edged OSU 12-10 in Tempe a year later.
The Sun Devils are playing the Cowboys instead of taking on LSU, which asked to move a previously scheduled series.
The Tigers and Sun Devils will play in Tempe in 2026 and in Baton Rouge in 2029.
Arizona State also announced a future football home-and-home series against San Diego State in 2027 and ’28 as well as a home game against Kent State in 2019 and Southern Utah in 2023.
