British prospects Callum Smith and Luke Campbell will be hoping to make an impact on their Stateside debut when they make an appearance on the undercard of the IBF welterweight clash between Shawn Porter and Kell Brook.

Neither super-middleweight Smith nor Olympic gold medallist Campbell has been placed in fights that are expected to pose a threat to their unbeaten records, but there will be an eagerness to perform in front of a new audience.

The chief support sees Sakio Bika attempt to defend his WBC super-middleweight title in his rematch with Anthony Dirrell, while Deontay Wilder will be hoping to record his 32nd successive knockout against Jason Gavern.

Below, Sports Mole takes a look at the main undercard bouts while attempting to make a prediction regarding the outcome at the final bell.

1. Sakio Bika vs. Anthony Dirrell

Eight months after their compelling encounter in Brooklyn ended in a draw, Sakio Bika and Anthony Durrell will do battle in Carson as they both look to move on to bigger and better things with the WBC strap in their grasp.

Dirrell has frequently stated that he deserved the win in New York, but his conservative style didn't attract many admirers on the night and that could see the American compete aggressively on Saturday night to leave the judges in no doubt that he deserves to be crowned the victor.

As for Bika, he has made a name for himself as being one of the most durable competitors in the division but he has regularly come up short when put in the ring with genuine world-class talent.

Dirrell has the potential to become a force at 168lbs, and if he learns from his mistakes in the first bout, he should have enough to edge a points decision, setting up the possibility of a showdown with George Groves in December providing that he can overcome Christopher Rebrasse.

2. Deontay Wilder vs. Jason Gavern

Earlier this year, Deontay Wilder made himself the mandatory challenger for the WBC title, but with champion Bermane Stiverne nursing an injury, that has left the American needing to keep himself active until a date can be agreed for his first challenge for the world crown.

The quality of names suggested as an opponent for Wilder was somewhat restricted given that his inclusion on the card came at short notice, but Jason Gavern is arguably the best of a limited bunch that were put forward to the power puncher.

It seems to be a near certainty that Gavern won't make it out of the opening three minutes but the 37-year-old has gone the distance with Steve Cunningham and seven rounds with Alexander Ustinov in the past two years.

Despite being a heavy favourite, complacency shouldn't be a factor to Wilder while he is defending his mandatory status, and a 32nd knockout will send another message to Stiverne that he is ready to make an impact at a higher level.

3. Omar Figueroa vs. Daniel Estrada

Despite being just 24 years of age, Omar Figueroa has quickly announced himself as one of the top figures of the lightweight division after stopping 17 opponents in 24 fights on his way to capturing the WBC title, but he suggested that he may have limitations in his last fight against Jerry Belmontes.

Figueroa was expected to coast past an opponent who had lost three of his previous five contests, but he struggled to a split-decision victory, with one card of 118-110 not doing Belmontes any justice after a credible performance.

Daniel Estrada is a step up from Belmontes, with a record of 32 wins and two defeats suggesting that he has the potential to dethrone Figueroa, but this will be the Mexican's first appearance outside of his home country and there is an expectancy that Figueroa will prevail by another points decision.

4. Callum Smith vs. Ahsandi Gibbs

Callum Smith has built himself a reputation of being one of the biggest punchers in the super-middleweight division as he attempts to move towards a world title opportunity in the next 12 months, but he was made to go the distance against American Vladine Biosse in his last fight.

That encounter saw the Liverpudlian show critics that he was more than just a knockout specialist and it will be beneficial for the 24-year-old to know that he has plenty in the tank should he fail to get his opponent out during the early rounds.

Like with Campbell, the purpose of Smith's trip to the States is to broaden his horizons ahead of sterner tests in the future, and promoter Eddie Hearn will be hoping that his fighter can begin to make himself marketable across the pond with several Americans beginning to move themselves into the mix for a world title.

Opponent Ahsandi Gibbs shouldn't provide Smith with too many problems, but before losing his last four fights, he had managed to rack up a run of 10 consecutive victories, so the Brit will need to be focused in front of what will be a sparse crowd during the early stages of the bill.

5. Luke Campbell vs. TBA

After a blistering start to his professional career, Luke Campbell's rise up the British lightweight rankings was temporarily stalled as he took a break from the ring for personal reasons, but the Yorkshire fighter returned in July with a routine points victory.

It wasn't the most sparkling of performances from the 26-year-old, but it enabled him to shake off any lingering ring rust ahead of fights to come, starting with his outing in California on Saturday evening.

Promoter Hearn is yet to formally confirm his opponent but he has revealed that it will be a Mexican fighter, and that should provide Campbell with new problems as he prepares to face Daniel Brizuela later in the year.
