Del Potro retired as a result of a fall during his third-round match against Borna Coric at the Shanghai Masters this week. The world number four looks unlikely to play in the season-ending showpiece in London next month after undergoing medical examinations on Saturday. Jorge Viale, the Argentine's spokesperson, revealed the 30-year-old was fitted with a splint on his right leg and will be informed by doctors of a recovery process in the coming days. "It's a very difficult moment. I feel very sad. It's a hard blow that leaves me without strength," said Del Potro, runner-up at the US Open last month. "It's very difficult for me to think about recovery again, I did not expect this to happen."
