UFC Fight Night 62 results: Josh Koscheck's future uncertain following fifth-straight loss

Josh Koscheck suffered his fifth-straight defeat, and second-straight submission loss, at the hands of talented welterweight Erick Silva in the pair's co-main event spot at UFC Fight Night 62 last night (Sat., March 21, 2015) in Rio de Janiero, Brazil.

Koscheck, a former Ultimate Fighting Championship (UFC) title contender, fought valiantly but couldn't overcome Silva's grappling, succumbing to a first-round guillotine choke (replay here). With the loss, "Kos" drops to 15-10 in the UFC and is one step closer toward retirement.

Coming into his 25th Octagon bout, the 37-year-old veteran was on the last fight of his ZUFFA contract (and fighting for his legacy) and at least maintained the possibility of competing again, whether he won or lost on fight night.

So, what's next for Koscheck?

Following his fight with Silva, he was seen on FOX Sports 1 -- in good spirits -- tossing out the idea of obtaining a commentating gig on the very same channel.

Koscheck also joked with UFC President Dana White about fighting someone his own age. "There aren't many of those [guys] left," White would respond during the post-fight press conference (watch it), while also pushing the notion of retirement.

The Ultimate Fighter (TUF) season one standout created a memorable legacy for himself on the combat sports reality show as well as in the cage. Koscheck first entered the Octagon a dominant collegiate wrestler, with loads of untapped potential.

The American transformed himself from pretender to contender over the course of his first four years in the promotion. Koscheck would pair a strong wrestling base with a stinging right hand.

He methodically rose to the top of 170-pound division, beating up the likes of  Dustin Hazlett, Frank Trigg, and Paul Daley. Then, in December 2010, Kos was awarded with a title shot against the greatest welterweight champion in UFC history, Georges St-Pierre.

Their tussle at UFC 124 was a rematch of their previous fight three years prior in which the Canadian outwrestled Koscheck. While he would prove to be the better wrestler four years ago, St-Pierre was once again levels above the California-based fighter.

A powerful jab from St-Pierre completely took Koscheck out of the fight for the entirety of their 25-minute affair and also broke his orbital bone. Following the title loss, "Kos" only amounted two wins, one of which came against then-declining UFC Hall of Famer Matt Hughes.

He's been finished in each of his last four fights and is no longer under contract with UFC. The division seems to have passed the once elite welterweight by.

No longer is Koscheck able to bang, nor is he able to manhandle the biggest of brutes at 170 pounds. All the intangibles, all his basic instincts -- the ability to survive and hang on -- are gone.

A fighter in a similar position is Dan Henderson. The former PRIDE champion is also on a major losing skid, but was recently booked to face Tim Boetsch at UFC Fight Night 68.

Hendo has more determination now than he ever has in his entire career, but often times an athlete doesn't know what's best for them. It's hard for any employer to tell them no, when they're not the ones who've spent years training in the sport.

At this point, both he and Koscheck are fighting off pure love of competition. Accolades and titles are far, far away from reason.

"Kos" wants to fight guys his age?

There are mixed martial arts (MMA) journeymen like Brian Ebersole, Joe Riggs, Mike Pyle and Josh Burkman who would all provide appropriate challenges.

Although he never won gold, Koscheck will be remembered for being one of the first modern day heel characters in mixed martial arts (MMA). His feuds with Chris Leben and St-Pierre gave fight fans laughs, as well as headaches.

His propensity for underhanded tactics (i.e., Anthony Johnson, Paul Daley) also lent themselves to building his bad guy aura. Whether it's the studio, or the cage that's next for him, he'll undoubtedly do well.
