Cordel Littlejohn committed to Illinois on Thursday evening through a tweet.
Littlejohn is a 6-foot-4, 190-pound dual-threat quarterback from Roswell, Georgia. He also had an offer from Tulane.
The Illini offered Littlejohn back in February.
Illinois now has 14 commits in the Class of 2018. Littlejohn is the first commit in the class not from Texas, Florida or Illinois — three states that head coach Lovie Smith has established as his strengths in recruiting.
