Irish MMA veteran Paddy Holohan today announced his retirement as a pro MMA fighter. The decision comes as the result of a rare medical condition, which the Irishman has apparently kept relatively secret until now.

Holohan released the following statement via Facebook:

I’ve known this announcement was coming for a week or more now and it has only felt worse the more I have thought about it.

I am forced to retire from MMA.

I was born with a factor missing in my blood called Factor XIII. I never disclosed it then or now, it came to the UFC’s attention from a third party and I can no longer pass the medical requirements to compete, only 1 in 5 million people are diagnosed so I knew that it was so rare, organisations wouldn’t understand or take the chance with me as I have found out now, I never explained in full to John or my team the actual risks cause I didn’t think there was excess risk .

It is a disorder that is only dangerous for me not my opponents.

I really did see MMA as the way to have a real shot at life for myself and my family and it turns out I was right.

I have mixed emotions about it:

Proud because I always wore my heart on my sleeve, stood my ground, never cheated, never turned away from diversity or challenges and always strived to inspire and encourage people from all backgrounds.

Sad because I will never make that walk again, under those lights, feeling all those uncomfortable yet life giving feelings as they count and you hear “walk walk walk” staring into a camera, knowing millions are watching but most importantly the Irish are watching.

I am also disappointed because people who have cheated within the sport due to PEDs etc putting their opponents in extra danger will fight again, whereas for me it’s a genetic 1 in 5 million disorder that stops me dead in my tracks.

I really feel I was only turning the corner in my fight career and I still have so much more to give!

Thanks to all of my team over the past 9 years at SBG. My coach John who backed me regardless when I had nothing but effort to offer him in payment, it’s been an incredible journey for this council kid!

To all the Irish people and people of my home town of Tallaght who have always caught my falls and helped me back to my feet, I am forever grateful to those people who have backed me through thick and thin.

This journey has made me the man I am today.

Paddy ‘The Hooligan’ Holohan.

Holohan was due to face Willie Gates at UFC Fight Night 87 in Rotterdam, Netherlands on May 8th. The UFC have confirmed they are currently securing a new opponent for Gates following Paddy’s announcement.

Paddy Holohan retires from MMA with a pro record of 12-2-1. He went 3-2 in the UFC, most recently losing to Louis Smolka via submission last October in the UFC Fight Night 76 main event.
