As of Tuesday afternoon, CU and CSU had sold more than 64,000 tickets between them for Friday's game.
CU reported it has sold 33,656 tickets (9,141 of those to students), while CSU had sold 30,472 (8,001 to students). Both teams are well ahead of their sales pace of a year ago.
In addition to tickets sold by the teams, the Broncos have a portion of tickets to sell, as well.
Last year's attendance was 69,850, the most since 2003, and this is likely to be the first time over 70,000 in sales since that 2003 game (76,219).
