Marcelo Guimaraes series of boils.
Brazilian fighter Marcelo Guimaraes had to go under surgery 8 days before his bout against Lim Hyun-Gyu in UFC ON FUEL TV 8 in order to remove up to 10 boils(furunkles) from under his right arm pit. The heavy anti-biotics treatment wasn't enough.
Some will jump and say that is just another Brazilian excuse for the bad performance and the loss. I will just say that showed a lot of determination from Guimaraes part.
That looks painful...
