Video: Watch UFC Fight Night 85 headliner Frank Mir turn out Todd Duffee's lights

After four straight losses over a nearly two-year stretch, Frank Mir had been all but written off as a serious heavyweight contender.

But then, after a year off, he came back and knocked out Antonio “Bigfoot” Silva in Brazil. And while some may have written that off as a fluke, Mir seemed to put that talk to rest his next time out.

In the main event of UFC Fight Night 71 this past July in San Diego, Mir stood toe-to-toe with fellow big man Todd Duffee – something not many expected out of him, given he had a distinct advantage on the ground.

But instead, Mir traded with Duffee and after they both staggered each other, it was Mir who landed a single punch that put Duffee face first into the canvas for his second straight “Performance of the Night” bonus and an affirmation that he was back as a threat in the UFC’s heavyweight division.

Later this month, Mir (18-10 MMA, 16-10 UFC) returns looking to get back in the win column after a close decision loss to Andrei Arlovski that some analysts scored in his favor. And just our luck: He’ll be taking on another fan of the rock’em-sock’em robots style of fight he had with Duffee – Mark Hunt (11-10-1 MMA, 6-4-1 UFC).

The two headline UFC Fight Night 85 at Brisbane Entertainment Centre in Brisbane, Queensland, Australia. The event, which airs on FOX Sports 1 following early prelims on UFC Fight Pass, takes place Sunday, March 20, in Australia but airs Saturday, March 19, in North America due to the time difference.

But before Mir heads to the “Land Down Under,” watch him put Duffee on the canvas in San Diego in the video above.
