After leading Butler University to consecutive Final Fours, junior guard Shelvin Mack has decided to stay in the 2011 NBA Draft, a source with knowledge of the decision told Yahoo! Sports.

Mack started to inform people of his choice on Saturday and is expected to hold a news conference with his college coach, Brad Stevens, on Tuesday in Indianapolis. The deadline for underclassmen to stay in the draft or return to college is Sunday.

Front office executives and scouts project Mack as a late first-round to early second-round pick.
