In their absence, Stefanos Tsitsipas, Andrey Rublev and Casper Ruud have been confirmed as the final members of Team Europe ahead of the fourth Laver Cup, which takes place from September 24-26. Alexander Zverev, Matteo Berrettini and Daniil Medvedev will also represent Team Europe.
Team World, coached by seven-time Major champion John McEnroe, are yet to announce the final three members of their team.
Young Canadians Denis Shapovalov and Felix Auger-Aliassime will be competing in the event, as well as Uruguay’s world No.14 Diego Scwartzman.
The remaining players will be revealed later in the week, with hopes that Nick Kyrgios will return for the fourth time in a row as the event comes to the TD Garden, home of his favourite NBA team the Boston Celtics.
The Laver Cup has produced countless memorable moments over its past three editions, most famously when Federer and Rafael Nadal found themselves on the same sides of the net for the doubles.
