A promotion linked to Daniel Kinahan since its inception is to stage a world title fight in Liverpool on Friday night.
Probellum, who moved to distance themselves from the mob boss after the US imposed sanctions on the Kinahan cartel, stage an 11-fight card at the M&S Bank Arena in the city.
They said in a statement after the santions were imposed: "Probellum takes the sanctions made by the US Treasury extremely seriously and the business and its employees will be fully compliant with them.
