MMA fighters, including former UFC champ, get into wild melee at Abu Dhabi hotel lobby

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. Usman Nurmagomedov then slapped him across the face, and all hell broke loose.
