Diego Nunes has been having a rough time lately having been released from the UFC after mixed results in the Octagon, then suffering back-to-back losses in the Bellator promotion.

Last night in Sweden at Superior Challenge 11 he looked to be in danger of heading for yet another defeat against Joachim Hansen after badly damaging his knee in the first round.

Despite having to limp aound the cage Nunes continued to fight on and his perseverance paid off mid-way through the second round when he stumbled backwards under pressure from Hansen then planted his feet, swung for the fences and landed a hard left hook that sent his opponent crashing face first to the canvas.

Nunes, who won the Superior Championship Featherweight Championship as a result of the KO confirmed afterwards that he believed he’d broken his knee.

The 35 year-old Hansen, a veteran of many of Japan’s top promotions over the years, has now suffered three losses in his last four fights with the last two coming via knockout.
