The 6-foot-3, 190-pound Hasani missed practice the last few days in an attempt to sort things out.
Hasani came to the United States in the end of the summer after playing at Gymnasium Sami Frasheri in Kosovo.
"Our thoughts are with Muhamed and his family,'' Rutgers coach Fred Hill said in a statement. "His well-being is our primary concern. He needs to go home and we support his decision to do so." His departure is not related to the downward spiral of the Scarlet Knights, who host Notre Dame today at 6 p.m., according to sources.
The situation comes a few days after Hasani returned to action Jan. 26 at Marquette. He missed a month after undergoing arthroscopic knee surgery.
In nine games, Hasani scored six points, with five of them coming against NJIT.
