Rafael Nadal participation at the ATP World Tour Finals has been placed in doubt having withdrawn from the Paris Masters due to “personal reasons”.
The Spaniard has battled health problems in recent weeks and was diagnosed with appendicitis shortly before the Shanghai Masters. He postponed surgery to remove the troubled organ to take part at the championship which he has never won.
He lost to Feliciano Lopez in Shanghai and two-weeks later began another campaign at the Swiss Indoors in Basel, where he racked up two comfortable wins over qualifiers Simone Bolelli and Pierre-Hugues Herbert to advance into the quarter-finals.
Up next for the French Open champion is wildcard Borna Coric on Friday but has now pulled out.
The Marjocan, who also forfeited his US Open title defence in August due to injury, is a major doubt for the 2014 ATP World Tour Finals in London, as organisers hope he continues postponing surgery.
Meanwhile US Open champion, Marin Cilic, has also withdrawn from the Paris Masters due to a right arm injury. Ernest Gulbis has opted out the championship, which takes place at the Palais Omnisport in Bercy, because of an injured right shoulder.
Croatia’s Cilic has already qualified for the ATP Finals, following his US Open triumph over Japan’s Kei Nishikori, but could finish outside the Top eight in the Race for London- potentially knocking the eighth-placed player out of the tournament.
British No. 1 Andy Murray, who will now be seeded in the top 8 at the Paris Masters in absence of Nadal and Cilic, will now hope for a good run to reach the World Tour Finals.
