Conor McGregor claims the lawsuit filed against him this week is "old news".
The UFC star is being sued by a mother and daughter in a multi-million euro personal injury lawsuit.
The claim was lodged on Monday in the courts by a young woman who has known the fighter for many years.
A second, smaller personal injuries claim has been lodged by the woman’s mother.
Responding to the claims in Abu Dhabi on Thursday afternoon, McGregor, who denies any wrongdoing, said: "It's old news. It was investigated thoroughly over two long years. And I was cleared of any wrongdoing."
Speaking ahead of his UFC 257 bout with Dustin Poirier, the Dubliner added: "There is so much positivity in my life and I have a great challenge ahead of me on Saturday night and I'm very excited to get in.
"I have put in an immense amount of work to get my frame correct at 155lb and to get my conditioning right.
"I want to answer questions here, I hope Dustin can bring it and that we can have a good fight."
A solicitor for the two women confirmed to Dublin Live that two sets of papers were filed to the High Court in Dublin on Monday and that McGregor is one of two men listed as defendants.
David Coleman of Coleman Legal Partners added that no further comment could be made on the case at this point.
A statement from Karen J. Kessler, spokesperson for the UFC fighter, said: "After an exhaustive investigation conducted by the Gardai which, in addition to interviews of the plaintiff, included: interviewing numerous sources, obtaining witnesses' statements, examining closed circuit footage and the cooperation of Conor McGregor, these allegations were categorically rejected.
"Mr. McGregor will dispute any claims and is confident that justice will prevail.”
