The game will be played at AT&T Stadium in Arlington, Texas, on Saturday, Sept. 4, 2021. Kansas State was previously scheduled to host Stanford at Bill Snyder Family Football Stadium in Manhattan, Kan., on the same date. “We were honored when AT&T Stadium contacted us about potentially playing in this prestigious game,” K-State Athletics Director Gene Taylor said. “The idea of taking a home game away from Manhattan and Bill Snyder Family Stadium is a big decision, and as a staff and university, we feel that it is an opportunity that we could not pass up.
