Conor McGregor kicked off the discussion ahead of a charity wheelchair boxing match with comedian and impressionist Al Foran.
Former UFC two-weight champion McGregor is set to face compatriot Dubliner Foran for the benefit of the Irish Wheelchair Association in a bout that was originally scheduled for September.
The 33-year-old is recovering from the broken leg he suffered in his second straight loss to Dustin Poirier at UFC 264 in July
It was originally believed that McGregor would fight two months ago in Galway as part of the event hosted by comedian Stevo Timothy. However, he withdrew from that September date on the advice of his doctor.
Speaking to Twitter today, McGregor confirmed the fight must continue – with the new date yet to be revealed.
The Notorious posted a photo of him throwing sitting punches and also took the opportunity to step up his infamous pre-fight smack-talk.
McGregor tweeted: “Today we begin preparations for my wheelchair boxing match for the benefit of @IrishWheelchair.
“Really excited to come in and have fun / smash celebrity impersonator Al Foran’s eyeball. Al, you can be Pacino! Joe Pesci! Even the great TyFury! But you just remain the fat Al of Tallaght to me. “
And Foran, responding insolently, tweeted: “From Portmarnock but whatever, need a trainer ASAP.”
McGregor, who has been active on social media during his injury, also offered an enigmatic response appearing to mock boxing today when asked about Canelo Alvarez’s rejection of his fight offer.
The Mexican made history on Saturday with an explosive 11th round victory over Caleb Plant to become the undisputed first conqueror at 168 pounds.
But when asked about a possible meeting with McGregor, Alvarez quickly decided to dismiss the rumors.
McGregor responded to Alvarez’s rejection of the fight offer on Twitter, when a user asked him what he thought of the Mexican’s comments.
The Dubliner wrote: “Fight or boxing? He then deleted the tweet.
