The 2004 Wyoming Cowboys football team represented the University of Wyoming as a member Mountain West Conference (MW) during the 2004 NCAA Division I-A football season. Led by second-year head coach Joe Glenn, the Cowboys compiled an overall record of 7âÂÂ5 record with mark 3âÂÂ4 in conference play, placing in a three-way tie for fourth in the MW. Wyoming was invited to the Las Vegas Bowl, where the Cowboys defeated UCLA. The team played home games at War Memorial Stadium in Laramie, Wyoming.
At quarterback, Corey Bramlet replaced his older brother, Casey, who graduated the previous season.
During the offseason, War Memorial Stadium was upgraded with new railings and improved handicap accessibility.
The big concern coming into spring training was the lack of depth on defense, a young and inexperienced offensive line and a poor running game. 13 starters and 38 lettermen returned. Fall practice began on August 11, 2004. The Cowboys participated in two intrasquad scrimmages. The first one was held August 21 and the second one five days later, on the 26th.
