How big is “The Deion Sanders Effect” in Boulder?

The CU Buffs, coming off a humbling 1-11 mark last fall, have sold out Folsom Field for fans to watch … practice.

The CU athletic department announced Thursday afternoon that no general-sales tickets remain for the annual spring game on April 22, making it the first sellout for the event in the annals of Buffs football. Per a university news release, a “limited number of student tickets” are available for current CU Student Sports Pass holders, but the rest are spoken for.

The spring game is slated to begin at 1 p.m. and will be the only college football spring event televised live on ESPN. CU alum Chris Fowler is on the call and will be joined by analyst and former NFL quarterback Robert Griffin and Quint Kessenich.

CU officials say the event will be the largest attended for a Buffs spring game, crushing the old record of 17,800 set in 2008.
