Ken-Flo could call it quits

Kenny Florian's mixed martial arts career could be coming to an end, according to a recent report.

Florian injured his back while weight training in November and has since been dealing with tingling and numbness down his right leg and has not been able to train.

"This back issue has been going on for a little while," Florian tweeted on Thursday. "We will see what (the) future holds."

Florian has met with several doctors -- an orthopedic doctor and a neurologist -- and they have suggested to Florian that he should retire.

"I've kind of been going back-and-forth with some of the doctors, so it's possible," Florian told the Boston Herald.

"I'm going to see. As of right now, obviously I can't compete and train like I was at all. I'm just kind of doing what I can and hoping that things heal up and get better. I'm just kind of in a holding pattern ... It sucks. The last couple of months I've just been figuring out what's going on and what I'm going to do."

Florian has had a successful career inside the Octagon (in several different weight divisions) as well as outside the cage as a commentator.

If Florian is in fact finished competing in MMA, the 35-year-old will retire with a 14-6 record and a career full of highlights fans can look back on fondly. Here are some of Florian's most memorable MMA moments.

Always a groomsman, never the groom

Florian probably dislikes the term "always a groomsman, never the groom" as his MMA career was a reflection of this. Florian challenged for a UFC title on three separate occasions, but came up without a belt each time.

In October of 2006 at UFC 64, Florian fought Sean Sherk for the vacant UFC lightweight title but lost a unanimous decision. After the loss to Sherk, Florian went on a six-fight win streak and climbed his way back up the lightweight ladder to a second title shot. However, at UFC 101 he was submitted by BJ Penn in the fourth round. The loss was the first and only time Florian has been submitted in his MMA career.

In 2011 Florian decided to drop to featherweight and take a run at the 145-pound title. After winning his debut in the division he earned a title shot against Jose Aldo, but fell short at UFC 136, losing a unanimous decision.

Also, early in his career, Florian came up just short of a TUF championship. He was TKO'd by a much bigger Diego Sanchez in the season one middleweight final of The Ultimate Fighter.

Ken-Flo's Canadian connections

The Massachusetts native has spent a lot of his professional career north of the border as he often trains in Montreal with Firas Zahabi, Georges St-Pierre, David Loiseau, and the rest of the team at Tristar gym.

In June 2006 Florian submitted London, Ont.'s Sam Stout with a rear-naked choke in under two minutes in the main event at the TUF 3 Finale. Stout was new to the UFC, riding a nine-fight win streak and coming off a big win over Spencer Fisher, but the veteran Florian humbled Stout with his crafty ground game.

Florian has provided the colour commentary for several UFC and WEC events in the past and twice those events took place in Canada. Florian helped call UFC 83 which featured a bout between Georges St-Pierre and Matt Serra that saw GSP regain his welterweight title. Florian was also an announcer at the first and only WEC that took place in Canada -- WEC 49, which featured an all-Canadian classic between Mark Hominick and Yves Jabouin.

At UFC 131 in Vancouver, Florian enraged (on purpose) the partisan crowd by sporting a Boston Bruins jersey during the weigh-ins. Boston and the Vancouver Canucks were in the middle of their Stanley Cup series at the time. Florian went on to defeat Diego Nunes by decision, much to the chagrin of the fans in attendance, and earned a featherweight title shot.

Elite competition

Although he never won a title, Florian competed against world-class competition for the duration of his career. He holds wins over the likes of former Pride champion Takanori Gomi, TUF 2 winner Joe Stevenson, and top lightweight contenders Clay Guida, Roger Huerta and Joe Lauzon.

Jack of all trades

In addition to being known as a well-rounded fighter, Florian competed in four different weight divisions in his UFC career. No other UFC fighter has accomplished this. He competed as a middleweight on the first season of TUF; he went 2-0 as a welterweight in the UFC in 2005; he made his biggest impact as a lightweight going 9-3 and earning two title shots; finally he made the drop to featherweight and earned a title shot in that division as well.
