Breaking: Joe Duffy suffers concussion in training, UFC Fight Night 76 main event scrapped

Joe Duffy has been forced out of upcoming UFC Fight Night 76 main event, according to UFC.com, which today shared the bad news.

Check out the statement:

"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. 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."

According to the report, Dustin Poirier -- who trained to battle the Irishman for 10 weeks -- has requested to compete at a future event rather than accept a new opponent on just 3.5 days notice. UFC Fight Night 76 takes place this Saturday afternoon (Oct. 24, 2015) inside 3Arena in Dublin, Ireland.

Fans who want refunds now that the main event and original co-featured fight of the night between Stipe Miocic vs. Ben Rothwell (read full details here) have both been canceled should "go through Ticketmaster at the point of purchase."

Poirier quickly issued the following statement via Twitter:

I'll wait to reschedule. This is the guy I've prepared to fight for the last 10 weeks https://t.co/R7l54l6ANG
