Yesterday the MMA world watched on as Anthony ‘Rumble’ Johnson stepped into the Octagon to face Alexander Gustafsson in Sweden.

Johnson did what many didn’t think he would, knocking out Gustafsson in the 1st round, marking the first time ‘The Mauler’ was stopped with strikes in his MMA career.

Below is a compilation of fighter reactions to the bout.
