Alexander entered his name in the draft on April 9, but left open the option of a return to WVU.
"I've used the last few months to explore my NBA options, and I've received a lot of positive feedback from NBA teams," says Alexander. "After evaluating the positive feedback and speaking with Coach Huggins and my father, I believe the best thing for me to do is stay in the NBA Draft. I'll cherish the memories I had at West Virginia University. Even though I'm leaving, I'll always be a part of the WVU family."
As a junior, Alexander led the Mountaineers in scoring at 16.9 points per game and in rebounding at 6.4 boards per game. WVU finished 26-11 and advanced to the NCAA Sweet 16.
"We are very supportive of Joe's decision," says Coach Bob Huggins. "Joe went through the process in a systematic and professional manner by exploring the situation and leaving open his option to come back. I've said all along that Joe has 100 percent support from the Mountaineer basketball family."
The NBA Draft will be held on June 26 at Madison Square Garden.
