Right before his main event fight on Saturday night against Tony Ferguson at UFC 216, Kevin Lee walked out and entered the Octagon with a visible lump on his left chest. Analyst Joe Rogan immediately took notice, speculating that it could be a case of staph infection.
Lee did admit during his post-fight interview with Rogan that it was indeed that infection. In his post-fight scrum with the media, he also stated that he was trying to conceal it from officials to avoid the risk of his fight being called off.
