FOUR days removed from a competitive 12-round decision win over Patrice Volny to headline Matchroom's Orlando show at the weekend, resurgent middleweight contender Austin 'Ammo' Williams has a new opponent tabbed.

Williams (18-1, 12 KOs) was ranked in the world's top-10 with three of the four major sanctioning bodies before his second victory in four months as the American rebuilds after an 11th-round stoppage defeat by Hamzah Sheeraz in Riyadh last summer.

The IBF have now ordered him to face the fifth undefeated boxer of his pro career in Italy's Etinosa Oliha (21-0, 9 KOs) next, with the two sides and their respective camps given 15 days - Thursday April 3 - to agree terms and avoid a purse bid being ordered.

News of the bout matchup was first broken by Jake Donovan.

Oliha is promoted by Agon Sports, while Williams' allegiances lie with Matchroom Boxing and he's managed by Sam Katkovski, who is listed as the matchmaker for next month's Astana bill where WBO/IBF titlist Janibek Alimkhanuly (16-0, 11 KOs) defends against France's 14-0 contender Anauel Ngamissengue.

No. 2-ranked Oliha was originally slated to box No. 6-ranked Kyrone Davis (19-3-1, 6 KOs) in the same slot this spring, in Oliha's native Italy.

Oliha, who held and made one defence of the IBO world title now occupied by Chris Eubank Jr, ended a three-fight decision streak with a third-round stoppage win over 21-3 contender Alexander Pavlov in Germany last September, where he's boxed exclusively over the last two years.

Davis hasn't boxed since notching a 10-round split decision win over then-unbeaten contender Elijah Garcia, who returns in Las Vegas this weekend on the Sebastian Fundora vs. Chordale Booker undercard.

Although they previously agreed a European trip for this contest, Premier Boxing Champions-backed Davis' handlers unsuccessfully sought to have the fight relocated to the US.

The sanctioning body now considers Davis "unavailable", and Williams was the highest-ranked available contender in their rankings, most recently updated on March 11.

Janibek already scored stoppage victories over former champion Vincenzo Gualtieri (#5) and Andrei Mikhailovich (#8), while No. 3-ranked Eubank Jr has a two-fight series with Conor Benn starting April 26 that will occupy his 2025 plans.

No. 4-ranked Shane Mosley Jr has an uncertain future and appears to be targeting a different world title route after declaring free agency last summer, though No. 7-ranked Ngamissegue looks to produce a seismic upset on enemy territory in Kazakhstan on April 5.
