The reason for Henderson's suspension was listed by the team as due to his "total conduct during the 2012-13 season, SEC and NCAA Tournaments, and his behavior since the end of the season." However, reports have indicated that the mid-July suspension he received was for multiple failed drug tests. Henderson was also reportedly caught with marijuana and cocaine during a July traffic stop.
Henderson, 23, was the leading scorer for the Rebels last season with 20.1 points per game. He helped lead the team to a victory in the SEC conference title, earning the SEC Tournament MVP award before leading an upset of No. 5-seeded Wisconsin in the NCAA Tournament.
Ole Miss is scheduled to begin their season on Nov. 8 against Troy before playing conference games against Auburn and Mississippi State. Henderson is set to make his debut against Coastal Carolina on Nov. 16.
