Monday Morning Hangover: What's next for Dan Henderson after second knockout loss to Vitor Belfort in Brazil?

Another weekend of fisticuffs has come and gone, as UFC Fight Night 77 blew the roof off Ibirapuera Gymnasium last Saturday night (Nov. 7, 2015) in Sao Paulo, Brazil.

Plenty of fighters were left licking their wounds, including Patrick Cummins, who was dominated by Glover Teixeira in the co-main event of the evening (recap here). And Clay Guida, who was choked out in the opening minutes by Thiago Tavares (results here).

But which fighter is suffering from the worst post-fight hangover, now 48 hours removed from the show?

Dan Henderson

"Hendo" looked to make it two in a row as he took on Vitor Belfort in the headlining bout of the night. In order to do that, he had to first get through a hungry Brazilian who was out to prove he could win without the aid of testosterone replacement therapy (TRT).

No, the other one.

In the process, Henderson hoped to take the trilogy against his longtime rival. But it was not to be, as "The Phenom" gave everyone a case of deja vu, knocking Henderson out with a stinging head kick followed by brutal strikes.

See it again here.

The kicker? It was almost two years to the day that Belfort did the exact same thing to his former PRIDE FC stablemate, also in the opening minutes of round one.

The loss puts Henderson's mixed martial arts (MMA) future at a crossroads.

As it stands, Dan has one more fight remaining on his UFC contract. And seeing as how he's planning on riding it out, don't expect the 45-year-old fighter to call it a day before he lives up to his end of the deal. And even if UFC allows him to see it through, don't expect Henderson to call it a day.

And it's a shame, really, as Henderson -- as cliche as it sounds -- really doesn't have anything left to prove in the sport, as he's done more in his near 20-year career than almost any other competitor.

Though he never won a UFC world title, his resume rivals that of any other MMA fighter in history. Plus, he's left in his wake a bevy of highlight reel moments to keep fight fans entertained for years to come.

Like this one.

Of course, that was the younger version of Henderson, as the heavy-hitter has been a shell of his former self the last couple of years. In fact, "Dangerous Dan" has now lost six of his last eight bouts inside the Octagon.

Having said that, a title shot is pretty much out the window, which means if he continues to fight, he'll either be doing it for a paycheck or to finish up what is likely his final UFC contract. Whatever the case may be, fans across the globe can expect Henderson to fight at least one more time inside the eight-walled cage.

As far as who his next opponent should be, I'm at a loss, because pairing up Henderson with his potential final foe will be a challenge for UFC matchmakers, despite his recent struggles.
