Irish phenom Conor McGregor was hoping to rest his sprained knee and return to the Octagon by the end of the year, targeting Diego Brandao at UFC 168 on Dec. 28 in Las Vegas. The only problem with that scenario, however, is he doesn’t have a sprained knee. The UFC sent McGregor to Los Angeles to have an MRI done on his knee, and the results were not what anyone had hoped for.
