In 1992, the head coach of Panionios, Vlade Đurović, Janković's mentor from his Red Star days, was instrumental in bringing him to the Greek Basketball League club.

Janković thought he scored a basket on a drive to the hoop while being guarded by Panathinaikos player Fragiskos Alvertis.

In reaction to what he believed was a bad call at a crucial moment of a very important playoff game, Janković slammed his head hard against the padded concrete goal post.

Jankovic eventually died of heart failure at the age of 42 on June 28, 2006, while on a holiday cruise on the Greek island of Rhodes.
