UFC's Bruce Buffer, boxing's Michael Buffer on HBO's 'Real Sports' on Tuesday

They’re the two most recognizable names – and voices – in combat sports announcing. Now HBO is profiling Michael and Bruce Buffer.

The cable network’s long running sports newsmagazine program, “Real Sports with Bryant Gumbel,” which has been on HBO for more than 19 years, on Tuesday runs a feature about the Buffer boys.

Michael Buffer is the legendary boxing voice responsible for “Let’s get ready to rumble.” And Bruce is his half-brother and the UFC’s “Voice of the Octagon.”

“Real Sports” talks to both Buffers, as well as notable figures in boxing and MMA like Bob Arum and Lorenzo Fertitta, about their influence and personalities.

The episode, with interviews from Emmy Award-winning “Real Sports” correspondent Soledad O’Brien, debuts Tuesday at 10 p.m. ET/PT on HBO.

Replays of the episode then air throughout the week on HBO and HBO2, and it will be available on HBO On Demand from Wednesday through June 16.
