The ruling comes after sports promotion company CSI Sports asked the court to block the event, claiming it would suffer financial and business losses.The decision gives Mayweather more freedom to continue his exhibition plans despite several ongoing legal and financial issues. While the lawsuit is still active, the court’s latest order allows the exhibition to move forward, offering some relief to the unbeaten boxing legend as he looks to revive his comeback schedule.Federal court rejects request to stop Floyd Mayweather Jr exhibition boutFloyd Mayweather Jr scored an important legal victory after a federal judge denied CSI Sports’ request for a temporary restraining order against his exhibition fight with former kickboxing champion Mike Zambidis in Greece.According to reports, Judge Vernon S. Broderick ruled that CSI Sports failed to prove it would suffer “irreparable harm” if the event went ahead. The judge explained that damage to the company’s reputation or financial interests could potentially be addressed later through monetary compensation. Because of that, the court did not find enough reason to stop the fight before it happened.CSI Sports filed the lawsuit last month. The company claimed it had invested heavily in Mayweather’s future events. It reportedly paid the former world champion an advance of $4.65 million to secure exclusive promotional rights. Those plans included an exhibition with Mike Tyson and a professional rematch against Manny Pacquiao.However, CSI argued that Mayweather later signed separate agreements without its approval. These reportedly included the exhibition against Mike Zambidis and another deal involving the Pacquiao rematch. While the company eventually accepted the Pacquiao arrangement, it continued to challenge the Zambidis exhibition in court.Mayweather’s attorney, David Jonelis, welcomed the ruling. He said the legal action appeared to be an attempt to stop his client from continuing his career. He added that the court’s decision allows Mayweather to move ahead with the Zambidis exhibition while the larger legal dispute continues.CSI Sports, however, remains confident about its case. The company’s legal representatives said they respect the court’s temporary decision but still believe they will succeed when the lawsuit is fully heard.Mayweather’s future schedule remains uncertain. Reports suggest he could still face Mike Tyson in a postponed exhibition later this year after Tyson recovered from a hand injury. At the same time, the proposed rematch with Manny Pacquiao has also been delayed because of legal disputes and scheduling issues surrounding Mayweather’s camp.Away from the ring, Mayweather continues to deal with several legal and financial problems. Reports say he is facing felony charges related to an alleged bad check case. He has also been dealing with a multi-million-dollar tax dispute with the Internal Revenue Service.
