After each fight in the state of Nevada, the commission will issue medical suspensions that vary from a week to indefinite.  Usually, a standard KO, will get a fighter around 30-60 days off without contact.  6 months though…that is one hell of a medical suspension.  It is believed that Mayhem was given a 6 month Medical suspension because his nose was broken during the TUF 14 finale with Michael Bisping.  Although, at anytime, a DR. can revoke the medical suspension at their discretion.  Below is the list of medical suspension from the TUF 14 Finale.
