Former boxing world champion Jeff Fenech says that the August 31 bout in Bendigo between Jeff Horn and Michael Zerafa will be Horn’s toughest fight to date.

“I’ve gone from believing it was a fight that Jeff Horn will win to thinking it will be harder than the Manny Pacquiao fight,” Fenech said.

He was in Bendigo yesterday alongside protégé Brock Jarvis, who was announced on the undercard for the Battle of Bendigo.

The 21-year-old Sydney native has a 16-0 record in his professional career thus far, after first donning the gloves six years ago.

“I played rugby league in Sydney and was doing boxing on the side,” Jarvis said.

“I started to enjoy that more and had my first spar and fight and thought, I’m going to do this,” he said.

The 170cm super bantamweight fighter credits the tutelage of Fenech as being a great asset to his career to date.

“He’s very knowledgable and he’s been there and done it. He knows the sport inside out,” Jarvis said.

His opponent in Bendigo will be Filipino Ernesto Saulong, who recently went 12 rounds against Ryosuke Iwasa for the IBF World Super Bantamweight Title.

“He’s a strong, come forward guy. I think I’ll use my reach and size and box him,” he said.

Jarvis’ preparations have ramped up this week, after he was sidelined for three weeks following testicular torsion surgery.

“I’m back into it and haven’t lost any fitness,” he said.

The Battle of Bendigo undercard is beginning to take shape, with Bendigo locals Damien Lock and Lorrinda Webb slated to fight Joshua Butler and Nadya Nakhoir respectively at Bendigo Stadium.
