After the Hunt v Bigfoot bloodbath in Brisbane, we look at some of the most brutal fights in UFC history The early exchanges of Mark Hunt v Antonio Silva in Brisbane. WITH a brutal UFC Fight Night in Brisbane having reignited debate about the merits of MMA, mostly thanks to a bloody main event between Mark Hunt and Antonio "Bigfoot" Silva, we look at some of the ugliest fights ever seen in the Octagon. Mark Hunt (R) and Antonio Silva during their brutal Brisbane UFC bout. Krzysztof Soszynski vs Stephan Bonnar - UFC 110 The UFC's debut in Australia saw "The American Psycho" Bonnar pound out a trademark war with Soszynski at Sydney Olympic Park. Bonnar, famous for his fight with Forest Griffin that marked the UFC as a major player in the sports world, copped a punch to the nose and a vicious uppercut in the opening round. Yet the real damage happened in the third round, with both fighters locked together against the fence. Bonnar came off worse from an accidental headbutt and a cut to his forehead immediately started spraying blood. The cut was deemed too deep for him to continue, much to his dismay, and Soszynski won by TKO. Stephan Bonnar is examined by a UFC physician during UFC 110 in Sydney during 2010. The American's cut handed him a TKO loss against Krzysztof Soszynski. Randy Couture vs Vitor Belfort - UFC 49 A trilogy match between two all-time greats of MMA. In 2004, just seven months after losing the UFC light-heavyweight championship to Belfort on a cut, Hall of Famer Couture unleashed a trademark mauling. "The Natural" cut Belfort near the start of the second round and opened up the wound further by slamming away from top position throughout. Couture landed 131 of 154 total strikes, turning his white shorts red as Belfort bled heavily. One Couture punch rocked Belfort's head so hard that it sprayed the cageside camera with blood. After the third round ended, Belfort sat in dazed disappointment and the doctors soon decided he was done. UFC legend Randy Couture celebrates a win in the Octagon. Cain Velasquez vs Antonio Silva - UFC 146 Brisbane Fight Night against Mark Hunt was far from the first time "Bigfoot" Silva has found himself covered in a blood in a big UFC bout. After Velasquez lost the UFC heavyweight championship in 2011, he needed a bounceback fight. He was matched up with Antonio Silva, coming off a loss of his own, and the fight was a one-sided blood bath. Velasquez had Silva on the ground within seconds and just one minute in fired off a left elbow that immediately cut the Brazilian's face. The powerhouse Mexican kept unloading on the wound and at 3:36 the fight was over - but not before the Octagon mat looked like a CSI crime scene.

BJ Penn vs Joe Stevenson - UFC 80 "The Prodigy" Penn was a phenomenal fighter when at his best and his fight with "Daddy" Stevenson got real ugly, real fast. Within seconds in the opening round Penn had a knockdown. With just less than 40 seconds left in the opening frame, he sliced his right elbow across Stevenson's brow, immediately splitting him open. Blood quickly began spurting everywhere, blinding Stevenson and giving his cut men had some serious work to do. Penn mercilessly went after the wound. Midway through the second round Penn knocked him down again, took Stevenson's back, and in a moment that became an iconic photo, Penn choked him out - applying so much pressure that a stream of blood could be seen shooting from his forehead.

Jonathan Goulet vs Jay Hieron - UFC Ultimate Fight Night 2 They never became iconic names in the Octagon but Jonathan Goulet or Jay Hieron can hang their hats on a 2005 fight that was undeniably the bloodiest fight in UFC history. About 30 seconds into the second round, Goulet landed a knee that split Hieron's forehead. Within seconds the cageside doctor was checking it, yet the fight went on. The cut bled all over the mat, made worse with Hieron in top position dripping blood all over Goulet. By the end of the round, both fighters looked like horror movie victims. Hieron was allowed to go out for round three, but after Goulet cracked him with another knee in a few seconds in, referee Jon Schorle took another look and called in the doctor again. By then he'd seen enough. Bigfoot Silva and Mark Hunt get red in their Brisbane UFC fight.
