PTPA co-founder Novak Djokovic declined to be named in a suit accusing tennis' governing bodies and Grand Slams of ‘abusing their power.'

The tennis players' association co-founded by Novak Djokovic has sued the main groups that run the sport in a bid to gain more money and control.

Calling the groups in charge of professional tennis “a cartel,” the players' association co-founded by Novak Djokovic filed an antitrust lawsuit against the women's and men's tours, the International Tennis Federation and the sport's integrity agency on Tuesday in federal court in New York.
