His rival? A beast of a Belarusian boxer called Alexander Ustinov.
Ustinov (36) was in Dunedin yesterday as part of a promotional tour for his heavyweight fight against David Tua in Hamilton on August 31, and posed for photographs with Will.
The ''tale of the tape'' was no contest.
Will is about 1.52m tall and tops out at 35kg on a good day. Ustinov is 2.02m tall and 136kg, and looks like he could eat 10-year-olds for breakfast.
But the mild-mannered Ustinov, speaking through interpreter Katya Nosova, said his diet was nothing out of the ordinary.
''I don't have any special diets or regimes,'' he said.
''Just a good meal with lots of proteins and it all has to be balanced, with vitamins, vegies and carbohydrates. Otherwise, I just eat anything.''
Ustinov's scheduled fight with Tua is under a cloud after the New Zealand boxer suffered a calf injury earlier this week.
A decision on whether the fight will be delayed will be made today in Auckland, where both the Tua and Ustinov camps are based.
''If it's [delayed by] a couple of weeks, I would most likely stay here, and it would be to my advantage - I would have more time to prepare or train.
''But if it's a month or longer than a month, it's best to go home and come back, and if the fight does not happen at all, that definitely would be a shame.
''I've come all the way here. It's been great. I love the country, but I did not come here for a holiday - I came here to fight.''
Ustinov began his fighting career kick boxing, winning multiple K-1 titles around the world, and has now forged an impressive record in boxing.
''I got to the peak of my career in kick boxing - I had won pretty much everything I could win - and there was not much further I could move, so I thought, why not try boxing and do the same?''
Ustinov's professional boxing record now stands at 27 wins from 28 fights, losing only his last fight in an 11th-round knockout to Kubrat Pulev.
