You know those pesky personal problems Junior dos Santos cited as one of his reasons for being off his game at UFC 155 last month (Dec. 29, 2012) at the MGM Grand Garden Arena in Las Vegas, Nevada?

It turns out it was a rather huge one.

Aside from his creatine issues, "Cigano" has revealed he's ended his 10-year marriage to his wife. Guilherme Cruz of Tatame has the word via Twitter:

Cigano has ended his marriage of 10 years with Vilsana before the fight with Velasquez. This was his "personal problem."

Dos Santos was on the receiving end of one of the most brutal one-sided title fight beat downs in recent memory courtesy of the newly crowned Ultimate Fighting Championship (UFC) heavyweight champion Cain Velasquez.

Cain dominated the fight from the opening bell, taking down the Brazilian bomber at will and even outclassing him on the feet, sending him crashing him to the canvas early in the first round with a perfectly placed right hand.

Junior went on to survive the early scare, only to be battered and bruised for four more rounds, which earned Cain a clean sweep on the judges' scorecards.

The loss was "Cigano's" first inside the Octagon since making his debut in 2008 and vowed to come back stronger than ever in hopes of getting a rematch, sooner rather than later, against the same man he knocked out in just over a minute in 2011.

While fight fans are quick to dismiss any "excuses" a fighter has to share after a loss --- and not to discredit Cain's outstanding performance, of course --- it's fair to say anyone going through the turmoil of a divorce right before a big fight probably won't have all their ducks in a row, either.

What say you?
