Reduced playing time has led Colorado running back Demetrius Sumler to opt to transfer before his senior season.
Several Colorado newspapers have reported that Sumler, who plans to graduate in May, will be looking for a chance to play more in his final season of college eligibility.
The Denver Post reported that Sumler's carries dwindled last season as he was used primarily as a blocking back in passing situations.
Sumler had 36 carries for 128 yards and a touchdown last season. He did not play in the Buffaloes' season-ending loss to Nebraska and had no more than two carries in any of the Buffaloes' final seven games of the season.
His best season came as a redshirt freshman in 2007 when he rushed for 335 yards and four touchdowns. Sumler showed much early promise by rushing for 85 yards against Colorado State in his first college game and 91 yards against Miami (Ohio) later that season.
But his playing time diminished as coach Dan Hawkins began leaning on Rodney "Speedy" Stewart and Brian Lockridge this season.
The Boulder Daily Camera reported that Stewart's departure will make him the ninth scholarship player to transfer from the Colorado program in the past calendar year.
His announcement places pressure on Hawkins to add some backfield depth in the upcoming recruiting period. Signing day is Feb. 3.
