Event organizers announced Friday that Djokovic will participate.
He won Wimbledon this month for his 21st Grand Slam title. That puts him one ahead of Federer and one behind Nadal for the most by a man in tennis history. Murray owns three major championships.
That quartet has combined to win 66 of the past 76 Grand Slam trophies, and each has spent time at No. 1 in the ATP rankings.
The fifth edition of the Laver Cup, which was founded by Federer’s management company, will be in London on Sept. 23-25. Team Europe is 4-0 so far.
Three members of Team World’s roster have been announced: Felix Auger-Aliassime, Taylor Fritz and Diego Schwartzman.
