Floyd Mayweather faces lawsuit aiming to block upcoming exhibition fight

Floyd Mayweather is dealing with a legal challenge after CSI Sports Events filed a lawsuit seeking $4.65 million in damages for breached contracts related to planned fights with Mike Tyson and Manny Pacquiao. The lawsuit seeks to prevent Mayweather's scheduled exhibition match against Mike Zambidis in Greece on June 27. CSI claims it made substantial advance payments to secure promotional rights for both fights, which fell through due to injuries and alleged violations of agreement terms by Mayweather. The case, initiated in a New York federal court, highlights uncertainties surrounding Mayweather's future exhibition events and potential ramifications for a Pacquiao rematch.
