Shortly after the trip, Orris, a 6-foot-3 guard out of Crete (Ill.) Crete-Monee, gave Illinois a verbal pledge.
Illinois Old School coach Scott Lidskin confirmed the news to Scout.com.
"Michael felt that it was a good fit," Lidskin said. "It's not far from his home. It's an hour and a half away. He really likes the coaching staff."
Lidskin said Orris also considered Nebraska, Boston College, Virginia and Northern Illinois.
"They feel that Illinois is going to be a real good team," Lidskin added. "They feel they are going to have a real good chance to get to the NCAA tournament every year."
Orris is Bruce Weber's first commitment of the 2012 class.
