Kei Nishikori replaces del Potro in ATP Finals

Vastavam web: Kei Nishikori will compete in the ATP Finals in London following the withdrawal of Juan Martin del Potro due to a right knee injury. The Japanese player joins Novak Djokovic, Rafael Nadal, Roger Federer, Alexander Zverev, Kevin Anderson, Marin Cilic and Dominic Thiem at the elite eight-player event, which starts on November 11.

Del Potro, who reached a career-high ranking of number three earlier this season, injured his knee while competing at the Shanghai Masters last month. “It’s a very special tournament and I’ve tried everything possible to get my knee better. The rehabilitation is making good progress but I need more time.”
