Quade Cooper will make his third foray into the boxing ring in tonight's Anthony Mundine-Danny Green undercard.

Cooper has won both of his professional fights so far and will take on Jack McInnes at the Adelaide Oval.

The Queensland Reds star joined McInnes at Thursday night's weigh-in for the fight, and his opponent revealed he had not shown up in the greatest shape.

McInnes is a 22-year-old fighter from Queensland who is yet to taste victory in his two professional fights.

He reportedly has over 50 fights outside boxing, including muay thai and mixed-martial arts bouts.

McInnes has been stopped in his two career fights, both in 2016. He was knocked out by Daniel Amman (31-9) and Mark Flanagan (18-4).

The 22-year-old is trained by Craig Glover, who says his fighter will use his considerable ring experience as an advantage over the Wallabies playmaker.

"Quade will be fit, he's always been an athlete and I expect nothing less," Glover told the Fraser Coast Chronicle.

"I think his body will be fit and ready but the one thing Jack has on him is fight experience.

"Fifty-five fights under your belt compared to three is a heck of an advantage for Jack as long as we can hang in there in the fight."

Bookmaker give him little hope of victory. Cooper is a heavy favourite on all markets and is looking to continue his winning run inside a boxing ring.

Cooper's previous two fights were against Barry Dunnett (1-1) and Warren Tresidder (0-1).

When pictures of Cooper and McInnes facing off at the weigh-in were circulated on social media on Thursday evening, fight fans were not too kind to the young Queenslander.

Cooper-McInnes is just one fight on the undercard for Friday's Mundine-Green blockbuster.

Nader Hamdan and Trent Broadhurst will feature in a light-heavyweight contest, as Olympian Andrew Moloney and Tim Tszyu also make up the card.
