Michael Zerafa destroyed Jeff Horn in an upset for the ages in Bendigo as he beat the Queenslander by KO in the ninth round.
Zerafa rocked Horn with several big right hands throughout the fight but in the ninth he hit Horn with a flurry of punches in the corner to send the former welterweight world champ to the canvas.
Even after that the fight was allowed to continue as Horn took way more punishment than some thought should have been allowed.
Zerafa pummelled Horn in a win commentators said would change the 27-year-old's life.
"Life changing night of action for Zerafa," one commentator said.
Horn copped it all night and while the first round was a feeling out process Zerafa begun the onslaught in earnest in the second when he knocked Horn to the canvas.
Horn hit back hard in the third round rocking Zerafa with multiple left hands but that was the best he had to offer as Zerafa continued to dominate the fight with Horn only grabbing a couple of rounds.
Unfortunately for Horn he was also cut badly in the third round as the pair clashed heads and a massive cut opened up on his cheek.
When he won the fight Zerafa was immediately emotional and in tears, hugging his team and sinking to his knees.
"I can't thank you enough for giving me this opportunity," a teary Zerafa told Horn.
"I knew 10 weeks ago I could win this fight. I knew I could beat Jeff Horn."
Asked if he wanted to fight rising Australian star Tim Tszyu, Zerafa scoffed.
"Tim Tszyu… please," he said.
Horn paid tribute to Zerafa's toughness and lamented his own poor performance.
"I'm just a bit shattered," Horn said.
"I have had some ups and downs, this is definitely a down.
"I just felt really sluggish, it is really annoying using that as an excuse but I just felt like crap going into it.
"Well done to Michael, he outboxed me, landed those beautiful shots but I don't feel like it was the best me in there tonight.
"I felt a little bit off, heavy, sluggish, I don't know if it was something I did, something I ate, just wasn't the right me.
"I fought like crap just then but well done to Michael because he fought brilliantly."
