Saturday night’s UFC Fight Night 76 event in Dublin, Ireland has suffered a huge blow with the news that the main event has been scrapped due to an injury.

Ireland’s own Joseph Duffy is reported to have suffered a concussion in training and that’s left him unable to compete on Saturday’s card, and unfortunately the news comes on such short notice that the UFC have been unable to produce a short notice opponent to fight Dustin Poirier.

“Having learned that Duffy received a strike to the head during training earlier this week, UFC sent him for medical tests in Ireland for precautionary purposes,” reads an official statement from the UFC. “The results determined that Duffy suffered a mild concussion and due to the proximity of the fight this Saturday UFC will not permit him to compete. The health and safety of UFC athletes will continue to be the top priority for the organization. As such, UFC has respected standard athletic commission regulations, which recommend a medical suspension from competition as a result of the concussion.”

Duffy also issued his own statement on Twitter.

With the original co-main event between Stipe Miocic and Ben Rothwell also have been pulled on relatively short notice it’s left an already thin UFC Fight Night line-up looking exceptionally weak by the promotion’s standards with Dublin’s Paddy Holohan now headlining opposite Louis Smolka, while Norman Parke Vs Reza Madadi likely to step into the co-main event spot on the four fight main card on the UFC Fight Pass service.
