Why did UFC BJJ let Mikey compete with a staph infection?
From Fighting Matters
In this episode of the Fighting Matters podcast, Steve Kwan is joined by Jeff Shaw of Bellingham BJJ, Mike Mahaffey of Old Bastard BJJ, and Dr. Clayton Green, a board-certified dermatologist and BJJ practitioner. They get into what happened at UFC BJJ when Mikey Musumeci defended his title against Kevin Dantzler with an active staph infection, went back to the hospital right after the match, and defended the decision by saying he had covered the infection with spats. The conversation covers why staph is more dangerous than people realize, how the UFC has stopped fights like this before but didn't this time, and what gyms and competitors can actually do to be safer.
