McGregor pays tribute to Holohan, who is training with him in Iceland. Holohan has been told he can no longer pass a medical to fight in UFC because he is missing a blood-clotting factor called Factor XIII.
Shout out to my brother @paddyholohanmma on his successful career in the fight game! We had a heck of a time in Iceland training and toasting young success!! Tallaght and Crumlins finest! The game will never be the same!’
