Michael Dixon left the Missouri program amid two sexual assault claims.
Dixon has not been charged in either case.
"It's been a challenging few months and while I appreciate the support of many in the Mizzou community, including my coaches and teammates, it's in the best interest of me, my family and the University of Missouri for me to finish my career elsewhere," Dixon said.
Dixon was briefly suspended for violating unspecified team rules in December 2010 by former coach Mike Anderson.
The absence of criminal charges in both cases prompted a groundswell of support for Dixon's reinstatement among Missouri fans, with some Twitter posts calling for the school to "Free Mike Dixon."
