UFC's Fight Night 81 took place on Sunday night, and for 37-year-old fighter Matt Mitrione it was a painful experience.
The former NFL player suffered a TKO defeat to heavyweight rival Travis Browne with the latter landing a well-executed punch in the third round to set him on the way to victory.
It was another, seemingly innocuous, moment that has made the headlines today, however. That's after Mitrione was left with a golf-ball sized hematoma on his right eye after being on the receiving end of not one, but two pokes to the eye. Scroll down this article to see the damage.

Having blinked his way through much of the fight, and with doctors having assessed the damage during a break in the bout, Mitrione's eye looked like something out of a horror film by the end of the night.
The crazy swelling you see above was caused by a combination of the eye poke and a lethal punch landed by Brown later in the fight.
Browne has been criticised for what many see as his illegal moves, although it wasn't clear whether either of the eye pokes were intentional.
The referee opted not to take away points during the bout but Mitrione insisted after the fight that it would have been very different had his vision not been so severely impaired:
All in all, it was a rough night for Mitrione and the Illinois native will likely be walking around with an ice pack on his face for several days to come.
