Greek canoe and kayak champion Andreas Kiligaridis remains in a critical condition, after suffering a stroke in Poland. The 37-year-old champion traveled to Bydgoszcz to participate in a competition.

According to early reports, the athlete has fallen into a coma and the next few hours are critical. Should Kiligaridis not recover from the coma, there is a serious chance that the hematoma in brain could spread.

Kiligaridis, who had complained about a mild temperature, was found unconscious in his hotel room by team mate Michalis Papasavvas. Medical tests indicate that Kiligaridis had been suffering from aggressive form of leukemia.
