Preview: Tune-up expected for Katie Taylor against Karen Elizabeth Carabajal as bigger tests lie ahead

Croke Park it ain't.

Six months on from Katie Taylor's historic triumph over Amanda Serrano, it's back to more quotidian challenges for the Irish superstar.

Undisputed lightweight champion Taylor puts her IBF, WBA, WBC and WBO belts on the line in Wembley Arena against Karen Elizabeth Carabajal tonight but anything other than a comprehensive win for the Irish woman would be a huge shock.

Carabajal is undefeated in 19 fights but, aged 32, this will be her first bout outside of Argentina or indeed even against an opponent from another country. She has gone 10 rounds just three times previously. A headline contest in London is quite the leap.

It was therefore no surprise to hear her say that the chance to compete for four belts at once was "a possibility that we could never have imagined".

Despite recording her first two KOs in her last three bouts and the advantage of a couple of extra inches, Carabajal has faced nobody even remotely on Taylor's level.

Yesterday, Taylor called Carabajal "a tough Argentinian [that] has everything to gain in this fight and nothing to lose.

She told RTÉ Sport: "These fighters are always very dangerous so I know I will have to raise my game."

But the Bray woman, 36, will surely be targeting a rare knock-out win, as she did on her professional debut in this venue in 2016.

Taylor's unbeaten excellence is based on speed and precision more than power, with the result that she has stopped just six opponents in 21 victories so far. The last came over three and a half years ago against Rose Volante in Philadelphia.

Taylor is far too driven to take any opponent for granted. She was back in training "a few days" after that bruising split-decision win over Serrano, a 10-round sold-out Madison Square Garden epic
