Welsh featherweight Lee Selby will hope to move a step closer to a shot at the WBC title on Saturday evening when he headlines Matchroom Sport's 'The Second Coming' show in Cardiff.

Selby faces Romulo Koasicha in an eliminator for the world strap, and the 27-year-old is joined on the bill by Nathan Cleverly's cruiserweight debut against Guyana's Sean Corbin.

Elsewhere on the card, Gavin Rees will be hoping to bring his career to an end with victory over Gary Buckland, who overcame the former world champion earlier this year, while Callum Smith faces one of the toughest tests of his career against Tobias Webb.

Below, Sports Mole takes a look at the headline acts on a bumper card, while picking out the best bouts on the undercard at the Motorpoint Arena.

1. Lee Selby vs. Romulo Koasicha

After a slow start to his professional career, it was unknown whether Lee Selby would ever be able to work himself up to the level required to compete on the world stage, but a succession of notable wins has put him within touching distance of fighting for global honours.

Selby has some good scalps on his CV - including Stephen Smith, John Simpson and Martin Lindsay - but it wasn't until he battled his way past the game Viorel Simion that he displayed the qualities required to mix it with the best that the division has to offer.

He has since overcome Ryan Walsh and stopped Rendall Munroe to move onto 18 wins from 19 matches, but it's his encounter with Koasicha that will really give an indication of whether promoter Eddie Hearn is correct to hold him in such high regard.

Koasicha, a 23-year-old Mexican, has lost three times in 24 outings but he brings plenty of experience to the table and the South American has never been stopped.

Selby is justifiably the favourite, but this will be a different fight to his previous 19 appearances. His opponent is likely to stick with him for the duration, and when under pressure, he is going to have to find a way to secure a points victory that would open doors for the Barry-based combatant.

2. Nathan Cleverly vs. Sean Corbin

It has been almost nine months since Nathan Cleverly surrendered his WBO light-heavyweight title to hard-hitting Russian Sergey Kovalev, and the nature of the defeat resulted in the Welshman considering his future in the sport.

After months of contemplation, it was decided that Cleverly would move up to cruiserweight, but several injuries saw the 27-year-old pull out of numerous contests, including a Monaco showdown with the dangerous Illunga Makubu, but that could prove to be a blessing in disguise for a man looking to find his feet again.

Cleverly is a world-class operator but he needed to avoid being thrown into the deep end on his first showing in the higher-weight division, and while Sean Corbin will provide a significant test to Cleverly's chin, it's a matchup that should provide him with the perfect platform to showcase his talent without being pushed to the limit.

Corbin has been been stopped four times in 21 bouts, but he is heavy handed and will test Cleverly if given an opening. However, while he will be looking to make an explosive start at cruiserweight, Cleverly should rely on his boxing skills rather than power and if he sticks to a gameplan, he should finish the job in the middle rounds.

3. Gavin Rees vs. Gary Buckland

Gavin Rees has enjoyed a decorated career which has seen him become world light-welterweight champion, but three defeats in a row has convinced the 34-year-old to hang up his gloves after Saturday night.

There has been no shame in Rees's recent losses - he was stopped by Adrien Broner before being edged out by Anthony Crolla and Saturday's opponent Gary Buckland respectively - but it's been enough to tell the 41-fight veteran that it's time to step away from the ring.

The defeat to Buckland was particularly unfortunate as many had him winning the fight, but nevertheless, it went into the record books as a loss, and Saturday's rematch gives him a chance to gain revenge before enjoying retirement.

Buckland, who has 28 wins from 31 matches, will be considered the marginal favourite at the weekend, but expect Rees to do what he always does - leave everything in the ring - only this time, it will be for good and that could result in him gaining revenge in Cardiff.

4. Callum Smith vs. Tobias Webb

Super-middleweight Callum Smith is regarded as one of the biggest talents in British boxing, and his eight stoppage victories in 10 fights have already taken him to the brink of the top 15 with a couple of governing bodies.

A six-month layoff halted his growing momentum after winning the WBC international crown against Ruben Eduardo Acosta, but he returned with a bang last month when stopping the durable Francois Bastient inside three rounds.

He is expected to secure his 11th professional win on Saturday, but Tobias Webb is likely to provide him with his toughest examination so far, with a Prizefighter loss to Rocky Fielding in 2011 being the sole black mark on a 16-fight professional career.

His boxing skills are proven after picking up 12 wins on points, but his apparent lack of power may prevent him from imposing himself against the Liverpudlian, and the likely outcome is another stoppage triumph for the Merseyside fighter.

Undercard

Paul Smith, the older brother of Callum, is a late introduction on the Cardiff card, and he will be looking for a positive display against David Sarabia in preparation for a potential shot at Arthur Abraham's WBO super-middleweight title later this year.

The unbeaten Chris Jenkins, who has 14 successive victories at light-welterweight, will face Miguel Aguilar, who went the distance with lightweight prospect Scott Cardle in 2012.

Welsh welterweight Dale Evans is another who will be looking to progress his career when he goes up against Mark Douglas after getting the better of Erick Ochieng earlier this year.

Sports Mole will be providing live text commentary of the show, with coverage scheduled to begin at 7.30pm.
