Ryan Garcia is leaving no stone unturned in preparation for his upcoming clash with Conor Benn.‘King Ry’ makes the first defence of his WBC welterweight title against his fierce rival at the T-Mobile Arena in Las Vegas on September 12.Garcia vs Benn is expected to be a war of attritionGettyMany anticipate it to be a firefight for as long as it lasts, with Benn forcing the action and Garcia looking to walk his adversary onto his patented left hook.To prepare for the front-foot aggression of the marauding Benn, Garcia has drafted in battle-hardened veteran Angel Fierro as a sparring partner.A picture of the pair in the ring together was uploaded to social media by Mexican promoter Bxstrs Promotions.Reacting to the photo, one fan wrote: “That’s good sparring, right there.”Another commented: “Some real great work to start off camp.”A third added: “RG needs high volume sparring and he’s got it here.”Meanwhile, somebody else posted: “Looks like they both went to war.”Who is Angel Fierro?Fierro (23-5-2) is the perfect fit to help replicate Benn’s style.The Tijuana slugger sets a relentless pace from first bell to last and is a tricky inside fighter.He caused Oscar Duarte real problems the last time he stepped into the ring in May, and was perhaps unlucky not to get the nod.Garcia has been sparring with pressure fighter Fierro for the Benn boutX - Bxstrs PromotionsFierro did, however, miss weight by 3.4lbs for the Duarte fight.Prior to his last outing, Fierro was disqualified for kicking compatriot Abraham Cordero in the groin.And before that, he went to war with Isaac Cruz in one of the best fights of 2025.While he has lost three of his last five bouts, Fierro remains a dangerous gatekeeper who is capable of upsetting the divisional elite.Judging from both men’s marked-up faces, Garcia got some quality rounds in with Fierro that should serve to benefit him against Benn.Watch Boxing on DAZN*If you click a link in this boxout, we will earn affiliate revenueSign up to DAZN to access the definitive subscription for boxing fans.Upgrade to DAZN Ultimate from just £24.99/month, guaranteeing access to 185+ fights annually, a minimum of 12 pay-per-views at no extra cost, as well as every Lega Serie A match and other elite football access.Alternatively, DAZN Standard is just £15.99/month, with the caveat you will have to pay for pay-per-view events.Click here to sign up.
