What's been said?
Speaking before the fight, Taylor said: "I just can't wait to fight at this stage, where I'm seen as the underdog fighter.
"Whoever walks to the ring first or second, all that stuff is irrelevant.
"I'm just excited and hungry for the rematch. I can't wait to step in there on Saturday and perform the way I know I can."
Cameron said pre-fight: "I can’t be complacent, I’m never complacent.
"Katie is a great fighter and I know that all she wants is revenge, I gave her a first defeat, so for me I have to be better.
"Jamie and I have been watching it over and over, and I am sick of watching it because I did make so many mistakes, some bits of it I cringe at so I know that I have more gears to go through.
"I have to come back to Dublin, do the business again and then carry on with my career."
Boxing fans finally get to see the rematch between Chantelle Cameron and Katie Taylor TONIGHT - and SunSport will be bringing you round-by-round coverage.
Taylor will be out for revenge as she suffered her first professional defeat in their previous encounter last May.
It was a fight that was almost too close to call but ultimately, the judges scored the points in the favour of Cameron to ruin Taylor’s Dublin homecoming.
However, the former champion is confident that she can avenge the only defeat of her career but it won’t be easy as Cameron is undefeated in 18 fights.
And this includes becoming the first female undisputed fighter following her unanimous decision victory against Jessica McCaskii in 2022.
This has all of the minerals to be a blockbuster title fight, but before that, there are a few big names on the undercard for boxing lovers to get their teeth into.
