(Reuters) - World number three Dominic Thiem is "extremely sorry" for the way players conducted themselves at Novak Djokovic's Adria Tour exhibition event after which four players tested positive for the novel coronavirus, the Austrian said on Thursday.
Djokovic, Grigor Dimitrov, Borna Coric and Viktor Troicki tested positive after playing in the charity tournament in Serbia and Croatia, which drew big crowds and saw players pose for pictures together.
