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.

Novak Djokovic will enter Miami Open, the second Masters 1000 event of the year, as the No. 4 seed, positioned in the same semifinal bracket as No. 2 seed Carlos Alcaraz.

Meanwhile, it has been announced that Alcaraz and Djokovic will make their debut in Florida on Friday, March 21 (the time has not yet been defined). In case of victory, their third round is scheduled for Sunday 23 March, while on Tuesday 25 March all the matches valid for the round of 16 will be played.
