The openly transgender member of the George Washington women's basketball team, whose groundbreaking season was cut short by a pair of concussions, says he won't play in his senior year.
Kye Allums said the choice was his.
"I alone came to this conclusion," Allums said in a statement released by the university on Wednesday, "and I thank the athletic department for respecting my wishes."
The school announced that Allums "has decided that it is in his best interest to no longer participate in intercollegiate athletics."
The statement offered no further details, although GW said Allums has enrolled in classes for the fall semester. Allums did not immediately respond to an email request from the AP for an interview Wednesday.
Allums made international headlines when he announced before the start of the season in November that he preferred to be known as a man. He said he was putting off hormone treatments and gender-changing surgery so that he could continue to play for the women's team.
But he suffered two concussions early in the season and played in only eight games. He told The Associated Press in March that he had suffered a total of eight concussions, that he was having memory problems and that he was unsure whether he would be cleared medically to play his senior season. He said doctors told him that he were a football player, his playing days would certainly be over.
"I'm a fighter. I'm still trying to come back," he said at the time. "I really do want to come back and play."
Allums said last year he would seek gender reassignment surgery before his senior year and would receive hormone therapy after he finished his final NCAA basketball season in April 2012. There was no immediate word on if that schedule has not changed due to his status with the team.
As a junior, Allums averaged 6.8 points and 3.4 rebounds in 16.9 minutes per game. A year earlier, he started 20 of 26 games. He averaged 7.4 points and 4.6 rebounds in 24.9 minutes per game.
