The 6-foot-9 forward can play next season thanks to the graduate transfer rule.
Lee averaged 13.6 points and 8.6 rebounds this past season and posted 11 double-doubles.
Illini Playbook has confirmed that the Illinois staff is interested in Lee and will pursue him.
The Illini faithful are familiar with this type of roster addition since John Groce took over in the spring of 2012.
Forwards Sam McLaurin and Jon Ekey both joined the program as transfers immediately eligible to play.
McLaurin averaged 3.8 points and 3.4 rebounds with Illinois in 2012-13 after spending three seasons at Coastal Carolina. A three-year contributor at Illinois State, Ekey ranks fourth on the team with 7.4 points per game this season and will be remembered for his game-winning shot at Iowa earlier this month.
