Paris: Sergei Bubka Junior, a tennis player ranked 186th in the world, and son of pole vaulting legend Sergei Snr, has been seriously injured in a fall from the third floor of an apartment building in Paris.

According to a French website, Bubka, who dates Belarusian world No. 1 Victoria Azarenka, sustained multiple fractures after falling from his friend’s flat on Thursday.

The accident occurred when Bubka found himself locked in a bathroom. He tried to reach the next room through a window but lost his balance and fell.

The 25 year-old was rushed to the hospital and his condition is said to be non life-threatening.

The 6’2” player, renowned for his powerful serve, mostly competes on the Challenger Tour but achieved his best career result last season, reaching the second round of the US Open.

His best performances this year were to reach the final at the Vancouver Challenger event and the second round of the Miami Masters.
