Grigor Dimitrov said Sunday he has tested positive for coronavirus, just a week after he played an exhibition tournament alongside world number one Novak Djokovic.

Last weekend, Dimitrov took part in the Adria Tour event in Belgrade with Djokovic, world number three Dominic Thiem and Alexander Zverev, ranked 17.
