Injury keeps Nadal out of Montreal tourney

The National Bank Open lost some more star power on the eve of the tournament as five-time champion Rafael Nadal announced his withdrawal Friday due to an abdominal injury. The news came a day after the withdrawal of Wimbledon champion Novak Djokovic, who isn't vaccinated against COVID-19 and isn't allowed to enter Canada. The Spaniard was set to be the No. 2 seed at the ATP Tour event behind defending champion Daniil Medvedev of Russia, who now competes under a neutral flag. Medvedev, Carlos Alcaraz of Spain and Stefanos Tsitsipas of Greece are some of the headliners along with local favourite Félix Auger-aliassime of Montreal and Denis Shapovalov of Richmond Hill, Ont.
