UFC Vegas 54 main event against former UFC Light Heavyweight Champion Jan Blachowicz in a sickening end to an exciting contest.The Austrian-born Serbian brawler, 30, looked to be edging a feisty encounter inside the UFC Apex as the event entered the fourth of five scheduled rounds between the 205lb rivals.Although both men opted to use leg kicks throughout the contest, it was a seemingly innocuous step back onto the right leg of the younger fighter that forced the referee to wave off the bout - with a replay showing the ligaments of Rakic snapping backwards under his skin.Former UFC Bantamweight Champion Dominick Cruz said on commentary: "When you stop like that something bad has happened to your knee.
You don't know what it is... but it's not good."Adding: "What an awesome fight though man. It's sad that is how it goes down but this is what happens in practise a lot."With former UFC Middleweight Champion Michael Bisping said before describing the injury as disgusting: "He's not moving, he's not getting up."
