Conor McGregor has challenged football legend Paul McGrath and comedian PJ Gallagher to a boxing fight following their social media spat.
The UFC star came in for heavy criticism over the weekend after highlighting Gallagher's mental health struggles on Twitter, including from McGrath who called the former two-weight champion a 'bully'.
And now McGregor, 34, says he will face McGrath, 63, and Gallagher, 47, in "2 vs 1 boxing match in aid of mental health and anti bullying organisations.

He tweeted on Tuesday: "I challenge Pj and Paul McGrath to 2 vs 1 boxing match in aid of mental health and anti bullying organizations."
The argument appears to have started when Gallagher shared a video of an American TV presenter calling McGregor British, with the comedian saying: "Normally this kind of thing winds me up but they can have this lad."
Tweeting over the weekend, McGregor said: “@pjgallagher you sad little pox of a thing.
“Sit up and smile for a change will you, you sad c*** hahaha wife left you an all and your crying in the paper bout depression, posture like a prawn.
“Sad b******. I am Ireland. There’s blood on my flag useesoo”.
McGrath then wrote: "PJ take no notice of bullies, you’re loved by everyone.
"Whatever you do don’t let him get the better of ya pal. Stay well. Top Man. @pjgallagher @TheNotoriousMMA."
McGrath later commented: "Conor you need to find GOD and when you do knock on my door I will have the kettle on for ya… my good friend."
That prompted McGregor to then take aim at McGrath in a series of tweets, in which he referred to the 63-year-old as 'English'.
He added: "If someone comes at me I am going to fire back.
"What don't you get? I didn't start any of this.
"It was me being bullied originally. Yet you come online to call me a bully.
"Leave me alone. Bullies the lot of ya's! I have mental health too!"
McGregor later added: "Irish and proud whether they like it or not!"
McGrath revealed on Monday that the Crumlin native had blocked him on Twitter.
