Boxer Manny Pacquiao is set to sue Floyd Mayweather over comments from the American calling the Filipino a drugs cheat.
The pair's fight in March, which was to have been the biggest moneymaking fight in boxing history, is on hold after Mayweather insisted upon drug tests for the fight under stringent World Anti-Doping Agency procedures.
Pacquiao refused and the pair may now meet in a courtroom battle rather than the ring.
