Colorado athletic director Mike Bohn reported 8,437 tickets remained available for the season opener against Colorado State with about an hour left in the business day on Tuesday.
Bohn said he expects the game to sellout. He said sales are on a similar pace at this point with the last time the Buffs hosted CSU in Boulder to start the 2005 season.
Earlier this summer Bohn said the school had sold about 3,000 fewer season tickets than last year. He said that number continues to shrink as the season approaches.
