Maayan, 20, a sophomore guard, will return to Israel by Jan. 2 to be drafted into military service, a requirement for all Israeli citizens. He had been granted a 120-day waiver to begin the season and had applied for a second waiver to complete it, though it was not granted, Jewish Telegraphic Agency reported Wednesday.
Seton Hall coach Kevin Willard said he was disappointed with the timing of the Israeli government's decision to draft Maayan into service.
"Tommy has been and will always be a beloved member of the Seton Hall community," Willard said. "We will certainly miss him, and while we understand and respect his responsibility to serve his country, we are disappointed with the timing."
Maayan did not address the media after Tuesday's game against the New Jersey Institute of Technology but confirmed later on Twitter the game would be his last. He thanked teammates and coaches for his time.
Maayan averaged 2 points and 3 assists in 20 minutes per game over his year-and-a-half career at Seton Hall.
