Tickets for the Rocky Mountain Showdown will go on sale Wednesday.

The annual football game pitting in-state rivals Colorado and Colorado State will be held Sept. 1 at 6 p.m. at Sports Authority Field at Mile High in Denver.

CU fans can purchase tickets at or by calling 303-49-BUFFS.

This year's matchup, to be broadcast on the Pac-12 Networks, will be the 17th to be played in Denver. Colorado leads the all-time series with the Rams, 64-22-2, including 10-6 in Denver.

CU is seeking a third consecutive win in the series, something neither team has done since CU won three in a row from 2003-05.

Last year, CU routed the Rams, 44-7, as quarterback Sefo Liufau threw for 318 yards and a touchdown and ran for 66 yards, running back Phillip Lindsay ran for 95 yards and two touchdowns and the defense held CSU to 225 yards in total offense.

CU (10-4, 8-1 Pac-12 South) is projected by many publications to reach a bowl game for the second consecutive season. CSU (7-6, 5-3 Mountain West) is seeking a fifth consecutive bowl appearance and is expected to compete for a conference title.

Season tickets, single-game tickets and three-game mini-plans for CU are currently on sale.
