"Our stadium is here and available. I haven't seen an application but every application that comes is always welcome," Mr O Fearghail told the Herald.
UFC President Dana White said he wants the Crumlin fighter to stage his first ever title defence in Croker should he defeat UFC featherweight champion Jose Aldo in Las Vegas in July.
"He's a young athlete who clearly has a world following.
"Certainly we need to discuss with Conor when he wants to fight and when he wants the venue," Mr O'Fearghail added.
