Earlier on Monday, Russell said in a Facebook post "Well good bye Oklahoma. Time to find new home." Russell added that he was told, " [He] was a cancer to the team."
Russell, 6-foot-4, 310-pounder, transferred to Oklahoma last season from Trinity Valley Community College (Terrell, Texas) and appeared in only two games for the Sooners.
Russell's arrival to Oklahoma was delayed from January 2013 into August 2013 due to academic issues.
