Welcome to live commentary of Joseph Parker's heavyweight clash with unheralded American Shawndell Winters from Dallas, Texas.
The former WBO champion will be looking for a highlight-reel victory against a 39-year-old opponent who has never beaten a ranked fighter 13 career victories.
The 6ft 2 Illinois native holds a 13-2 record as a pro with 12 of those wins coming via stoppage,
But this fight is all about Joseph Parker and whether or not he can make a big enough statement to earn himself a potential WBO title eliminator against Oleksandr Usyk later this year.
The Kiwi hasn't fought since a June 2019 win over Australian Alex Leapai in Rhode Island.
But with heavyweight boxing being as unpredictable as it is, he finds himself ranked second in the WBO and once again in the conversation for a title fight.
The 28-year-old must keep himself in the headlines in a division that has seen three title changes in the last seven months.
Pre-fight banter : Hearn believes Parker is on cusp of contention
Matchroom promoter Eddie Hearn says Kiwi boxer Joseph Parker is one moment away from being back in the conversation in the heavyweight division.
Parker, who held the WBO heavyweight title in 2018, has struggled for a big-named fight since his back-to-back losses to Anthony Joshua.
He was set to fight Brit Dereck Chisora, before having to pull out three weeks before the fight due to injury.
"It's been a frustrating period," Parker's promoter Hearn said.
"That Chisora pullout has been a kick in the nuts, I feel it was the perfect fight for him,"
But Hearn says Parker's merely a big performance away from being back in the title scope.
"He's in a great position," Hearn said.
"He just needs the momentum back, it just takes one knockout for people to say he's a threat to the division again.
"Because at the moment, he's just stepped off the radar a little bit because of the inactivity."
The 28-year-old is fighting little-known American Shawndell Winters on Sunday, March 1 and Hearn thinks it could be the start of momentum-building phase for Parker.
"I think it's a good fight for him against somebody who's going to try, we know in the heavyweight division and where he's placed in the WBO and if it becomes available then it will be Parker against [Oleksandr] Usyk for the world title."
Hearn understands the dangers of fighting somebody like Winters.
"Winters is a bit crazy, he's not the full ticket, he just wants to knock people out."
