Johnson subsequently confirmed the news via Twitter.
CBSSports.com first reported Johnson was likely to land at Memphis last week.
Johnson led Vanderbilt in scoring during the 2012-13 season while averaging 13.5 points, 3.6 assists and 3.5 rebounds per game before being suspended "as a student" in July 2013 because of what the 6-foot-4 guard later described as a "mistake" he made that was the result of "some very poor judgement." The initial plan was for Johnson to serve his suspension, then enroll again at Vanderbilt. But that plan changed -- Vanderbilt coach Kevin Stallings suggested last week that Johnson wasn't wanted back -- and Johnson will now enroll at Memphis, which badly needs a veteran ballhandler considering not a single guard on the Tigers' roster has played one minute at the Division I level.
A source told CBSSports.com that Memphis will apply for a waiver to make Johnson eligible immediately. The school successfully appealed on behalf of Missouri transfer Michael Dixon last year under similar circumstances, which is among the reasons all parties believe Johnson will be in the lineup when the Tigers open the season against Wichita State.
