The record books could need changing come Saturday night as Northern Ireland's Carl Frampton aims to become the first three-weight world champion to come out of Northern Ireland.
Born in Belfast in 1987, Frampton was a star amateur on the domestic circuit and even went on to claim silver in the European Championships in Dublin back in 2007 before retiring from the unpaid ranks in 2009, with a rumoured record of 103 wins from 114 bouts.
His professional career started emphatically with 17 wins from his first 17 bouts but then it was time for "The Jackal" to take the step up to world title level and step up he did with a comfortable points defeat of Kiko Martinez for the IBF super bantamweight crown, a fighter he'd previously beaten 18 months earlier for the European title.
Frampton then defended the belt twice, overcoming two knockdowns in one of those fights against the late Alejandro Gonzales before becoming unified super bantamweight world champion with victory over arch-rival, Scott Quigg.
With the weight catching up with him, the 34-year-old immediately stepped up to featherweight after the Quigg fight to take on the then unbeaten Leo Santa Cruz and in typical Frampton fashion, he put on a masterclass of performance to become a two-weight world champion at the first attempt. Since then though he has lost two of his seven fights with a defeat in the rematch to Santa Cruz and then loss to Josh Warrington back in 2018.
A dominant performance over Tyler McCreary, who is extremely similar in physique to Herring, and a stoppage victory of Darren Traynor has followed, so he goes into his eighth world title fight with some momentum.
The main thing Frampton has to do to win this fight is close the distance on Herring. He can't step into range letting massive combinations go cause Herring will be too smart for that and be able to pick him off with counter punches off the back foot.
Frampton needs to think. He needs to hold a high guard, trick his way in with faints and then use his hand speed and noticeable power to get to work on Herring's body. If Frampton can find have success early on in the fight and make Herring somewhat smother his own work, he'll frustrate the American, and frustration often leads to mistakes and openings.
