After a one-sided loss to Tom ‘Kong’ Watson in the main event of BAMMA 6 last night in the UK, Murlio ‘Ninja’ Rua announced his retirement from the sport via Twitter.

“”I would like to announce officially my retirement from pro MMA fights,” he said. “It was an amazing run, and [it’s] a very tough moment, but there comes a time for all in life, and it’s time to move on. I am proud of all I did in MMA and all experiences I had. I will continue to work with MMA, doing seminars, [teaching] classes, training fighters, and doing my share to help our sport that I love so much. It’s time now to help others and enjoy my family, my wife, my kids and move [on].”

The 31 year-old was second-best at BAMMA 6 from the opening bell as Watson put on a virtuoso performance, with his leg and head kicks being particularly effective throughout the fight.

By the second round Rua was limping badly on his lead leg with his knee visibly swelling, but he showed tremendous courage to continue fighting regardless. It left him struggling to defend himself however and in the third round ‘Kong’ turned up the pressure and rocked him with a right hook, followed by a head kick and then a flurry of punches to claim the KO victory.

It was the second defeat in a row for Rua, who throughout his 11 year career fought for a number of notable promotions including PRIDE, Strikeforce, Cage Rage and Elite XC.

Despite a number of exciting fights he never reached the heights of his brother ‘Shogun’s’ career however, and he hangs up his gloves with a final record of 20-12-1.
