Novak Djokovic said on Thursday he is not named in the lawsuit filed by the Professional Tennis Players’ Association’s (PTPA) against the sport’s governing bodies as he wants other players to step up.

Why the lawsuit filed Tuesday exists, what it accuses tennis' governing bodies of doing and the next steps you can expect to see.

Novak Djokovic has sought to create some distance between himself and the legal action taken against the ATP and WTA tours by the players' union he formed, calling on younger players to take a stand.
