Reports initially surfaced on a Facebook fan page and Croatian newspaper Ve?ernji list confirmed the reports with Karlovic’s family. Karlovic’s father, Vlado, confirmed the reports to the press and was reportedly visibly upset because the family has yet to receive a definitive diagnosis from doctors.
The paper reports Karlovic was initially released from the hospital but was readmitted after falling ill again.
Karlovic is the tallest player ever on the ATP Tour at 208 cm (6 ft 10 in). Karlovic has held the record for the fastest serve recorded in professional tennis, measured at 251 km/h (156 mph) and is considered one of the best servers on tour. He has won 4 ATP singles titles on the tour.
Really hope, he gets well soon. My good wishes and prayers.
