A UFC rivalry appears to have been rekindled in Abu Dhabi this week ahead of an MMA event scheduled there this weekend. Former UFC bantamweight champion Merab Dvalishvili was jumped by MMA free agent Usman Nurmagomedov, the younger brother of Dvalishvili's former opponent, Umar Nurmagomedov, in a hotel lobby overseas. Dvalishvili was recording an interview for Real American Freestyle when Usman Nurmagomedov and others approached behind him.
