Horn KOs Mundine in opening round

The fight started late but Jeff Horn made sure everyone went home from Suncorp Stadium on time.

The ex-WBO welterweight champion's response to his first professional defeat at the hands of Terence Crawford in June was to end the 18-year professional boxing career of Anthony Mundine inside two minutes on Friday night.

After leaving fans waiting an hour past the scheduled start of the fight, Horn wasted no time once the bell rang.

The 30-year-old stung Mundine early with a big right hand to the body.

From that moment, the 43-year-old ex-rugby league player looked in trouble as Horn came at his older rival.

A few more hits were then followed by a left hook which slipped over Mundine's defence and caught him flush on the jaw.

Mundine fell and the fight was over, a win in 96 seconds by knockout.

The win was the comprehensive one Horn knew he had to deliver to respond to his critics after that humbling loss to Crawford in Las Vegas.

Confident in his performance at the 71kg catchweight, Horn said he now had to work out if his future lies at welterweight or explore options in heavier divisions.

"I'm not really sure what the next move will be," Horn said.

"I guess we've got to sit down and talk about that still."

Mundine, who said there was no amount of money which would get him back into the ring, praised his opponent and wished him the best for his future.

"I feel good, that's boxing man," Mundine said.

"It couldn't have went to a better guy. He's a genuine dude.

"I'm 43, I'm not 23 you know ... No excuse I had a tremendous camp. It couldn't have went to a better guy.

"God willing this guy can go on and do tremendous things."
