INDIANAPOLIS -- Butler guard Shelvin Mack formally announced Tuesday that he is staying in the NBA Draft.
Mack helped Butler reach the NCAA final the last two seasons. The Bulldogs lost to Connecticut in this year's national title game after falling to Duke in the 2010 final.
Butler officials said Sunday, the day of the deadline to pull out of the June 23 draft, that Mack wouldn't return for his senior season.
Mack finished 11th on Butler's all-time list with 1,527 points, was fourth in 3-pointers and fifth in assists. He averaged 20.3 points during the 2011 NCAA tournament and is the school's all-time tournament scoring leader.
Last year, Butler's Gordon Hayward left early, and the Utah Jazz picked him in the first round.
