Novak Djokovic canceled his afternoon practice session at Wimbledon a day after the seven-time champion had a "nasty" fall moments before clinching his quarterfinal victory.

Novak Djokovic is causing concern heading into his Wimbledon semifinal match against World No. 1 Jannik Sinner, after canceling his scheduled practice for this Thursday.
