A concussion was the cause of Ultimate Fighting Championship (UFC) Lightweight Joseph Duffy's reluctance to step into the Octagon and face the dangerous Dustin Poirier at UFC Fight Night 76 in Dublin, Ireland, last month.
However, the tilt was rescheduled and will now take place at the UFC 195 pay-per-view (PPV) on Jan. 2, 2016.
Former Flyweight title challenger John Moraga suffered his own concussion during a tussle with No. 1-ranked Joseph Benavidez at UFC 187 last May, but the difference between the injuries incurred by "Irish Joe" and the MMA Lab product is that the latter has been out of commission -- even from training -- for the last five-plus months.
Moraga's testimony from his Facebook account (via Bloody Elbow):
"I've been dealing with my own concussion since my last fight. Disconnected and dizzy is the best way to describe how I felt during the fight and afterward I knew something was wrong, I was just too dissappointed to dwell on it. At 7:00am the next morning I woke up from a crazy dizzy episode and had to go to the hospital. I was diagnosed with a concussion and sent home. Two months later after doing nothing and only resting, I tried to start working out again but things were still not the same. It turns out I had some inner ear issue and my balance was a total mess and I couldn't turn my head quick without getting nauseous and dizzy. I'm feeling like the therapy is finally starting to get me back to normal and I am expected to make a full recovery. Thank you all for the support."
Concussions are nothing to play around with as there has been cause for concern in other professional sports such as the NFL. In a report commissioned by Boston University and Department of Veteran Affairs (via PBS.org), 87 percent of deceased players were found to have the brain disease chronic traumatic encephalopathy, or CTE.
Brain trauma and the toll violence has taken in certain sports like professional football and MMA have seen some fighters reconsider their current career path.
Moraga, 31, boasts a 16-4 overall record (5-3 UFC), but has been served plenty of fists at a high velocity in three Octagon losses against Joseph Benavidez, John Dodson and flyweight champion Demetrious Johnson.
"Chicano" offered no timetable on his MMA return.
