A month or so ago they were selling them as part of their National Championship Package. But Cheri updates us that CU is selling single game tickets for next weekend.
There's a limited number available and they appear to be along the visitor's sideline. The band and bulk of the visiting Dawgs will be in endzone area adjacent to the athletic center.
Here's a direct link to the Buffs' website. I used an image of a seating chart that showed the sideline assignments but isn't too clear when it comes to section numbers. So here's a link to some other seating charts. Good luck!
