Auburn will limit attendance at Jordan-Hare Stadium to about 20% of capacity at the start of the football season.
Athletic director Allen Greene said the move will lead to "a shortfall of tens of millions of dollars this year.'' He noted that football revenue finances each of Auburn's 21 sports teams.
Auburn says all general seating tickets for the Sept. 26 opener against Kentucky will be reserved for students. That doesn't include controlled premium spaces or tickets designated for guests of home or visiting players and coaches.
Auburn will announce ticket allocations for other games later.
