In the end it took 96 seconds for Jeff Horn to deliver the comprehensive victory he knew he had to produce against Anthony Mundine.
- Jeff Horn emphatically knocked Anthony Mundine out inside the first round of the highly anticipated fight
- Mundine declares his "time's up" as a boxer following his ninth career loss
- Win for Horn comes as he tries to rebuild after 2018 loss to Terence Crawford
Horn may have been late to the pre-fight weigh-in at Lang Park due to Brisbane's Friday night traffic but he ensured a quick finish when he faced the veteran in the ring.
Mundine looked sluggish from the outset in the heavily anticipated bout, which started about an hour behind the scheduled 9:30pm start.
After copping several shots from a faster and stronger Horn, Mundine was floored by a left-hook which slipped past his right glove.
After the defeat Mundine declared his "time's up" as a boxer, with the defeat effectively ending his 18-year professional career.
"Jeff proved tonight he's the better man," Mundine said.
"That's the next generation, man. I was ready. I was prepared well. It's just boxing, you get caught sometimes."
Horn, who was aiming to rebuild his reputation after a first professional defeat to American Terence Crawford in June, said he was comfortable fighting at the 71kg catchweight.
"I feel really, really strong at this weight," the former WBO welterweight champion said.
"I was expecting a hard fight.
"I'm happy to get it over and done quickly."
Horn, who has indicated he'd be keen to organise a rematch with Crawford in Australia if possible, is also exploring the possibility of pursuing fights at heavier weight divisions.
