The International Tennis Integrity Agency (ITIA) has announced the suspension of three tennis players.

Belgian players Romain Barbosa, Arthur de Greef and Alec Witmeur have all been immediately suspended from partaking any activities on the circuit.

They are prohibited from competing in or attending any sanctioned tennis events organised by the governing bodies of the sport.

It is yet to be confirmed by the ITIA or the player, what exactly has happened but it is worth knowing that the ITIA normally reveal cases of "crimes” against the integrity of the sport, such as cases of doping, match-fixing, illegal bets or other fraud on the circuit.

Former No. 113 De Greef, who in January moved on from the court and has become a coach for Ysaline Bonaventure, world number 126, would have been in Paris this week to supervise her, as she competes in the qualifications for the French Open.

Bonaventure failed to qualify, losing to Romanian Monica Niculescu on Tuesday.
