There's video of the M'Pumbu TKO in the full entry.
Brian Hemminger described the Mann fight at MMA Mania:
In the feature bout of the evening, Bellator standout free agent featherweight Ronnie Mann put on a show against Nebraska wrestler Josh Arocho. Mann's adept ground game completely neutralized Arocho's wrestling, immediately popping up from takedown attempts as well as pulling off beautiful sweeps. Mann spent much of the three rounds pounding away on the American's face with elbows and punches from guard.
By the time the bout went to the judges, Arocho's face was a battered mess and Mann was awarded an easy unanimous decision, even winning the bout 30-25 on one judge's scorecard.
