Jono Carroll and Katie Taylor both put their unbeaten pro records on the line stateside in Philadelphia on the night of March 15.

Dublin southpaw Carroll headlines the card in the US state of Pennsylvania facing his toughest challenge to date in IBF super featherweight champion Tevin Farmer.

Hometown boy Farmer (28-4-1-1, six knockouts) has the advantage of being on his own turf. Carroll, who won the 2014 Prizefighter competition at lightweight, has since been crowned European and Intercontinental champion in the super featherweight class.

His first world title fight could hardly be tougher but Carroll (16-0-1, three knockouts) has boxed on some big occasions before.

A unanimous points victory over Miguel Gonzalez came on the undercard and in the build-up to Tyson Fury dethroning heavyweight kingpin Wladimir Klitschko in Dusseldorf back in November 2015.

Carroll fought Guillaume Frenois of France to a split decision draw in the Sheffield Area last time out, ending his perfect winning run of 16 consecutive victories in the paid ranks.

Farmer is the clear fancy at 1/10 in Mrgreen betting on the bout, with Carroll rated a 5/1 underdog and a draw 25/1. The prices on offer for this St Patrick’s Weekend clash reflect the difference between the two combatants.

American fighter Farmer has had twice the number of pro fights of the challenger and is just a couple of years older.

Although right-handed, Farmer boxes as a southpaw too and has developed a reputation for slick defence and an old school approach to boxing.

Two fights ago, Farmer stopped another Irish fighter in James Tennyson with a fifth-round knockout in his first official defence of the IBF strap.

Women’s WBF and IBF lightweight champion Taylor (12-0, five knockouts), meanwhile, seeks to unify another belt in the division when she tackles dangerous Brazilian fighter Rose Volante.

The London 2012 Olympic gold medallist faces the WBO champion with Volante also unbeaten (14-0, eight knockouts).

With three of the four lightweight belts up for grabs in this fight, the bout is more than just an appetiser on the Farmer v Carroll undercard.

While Volante no-showed the press conference to promote this unification bout, Bray native Taylor must take the Brazilian boxer seriously.

Taylor is a red-hot 1/2 betting favourite to add a third world title to her collection, while Volante is a 9/1 outsider and the draw priced up at 25/1.
