It is the second bout for 'The Destroyer' since his two failed voluntary drugs tests that forced the cancellation of a blockbuster grudge match with Chris Eubank Jr in October 2022 and sparked all the subsequent controversy and fallout.
Benn's first fight since brushing aside Chris van Heerden in Manchester in April 2022 came at late notice on a low-key bill in Orlando back in September, when he earned a unanimous decision win over Rodolfo Orozco following the lifting of his provisional suspension.
Benn - who insists he is innocent of intentionally doping having tested positive for the female fertility drug clomifene before his proposed clash with Eubank Jr - still does not hold a boxing license in the UK as he awaits the verdict of a British Boxing Board of Control (BBBoC) appeal against the lifting of that provisional UKAD suspension by the National Anti-Doping Panel (NADP).
That appeal is expected to be heard this month, but for now Benn is back Stateside for his latest tune-up against Dobson, an undefeated 33-year-old American welterweight whose professional record currently stands at 16-0 with nine knockouts.
New Yorker Dobson has not fought since the summer of 2022 though, when he outpointed Argentine southpaw Rodrigo Damian Coria in Atlanta.

Benn vs Dobson fight prediction
Despite his long layoff, it was a surprise to see Benn go the distance with a little-known opponent in Orozco last time out.
However, he seemed grateful for the rounds under his belt as he plots his way back to relevance, this week calling out the likes of Devin Haney, Jaron 'Boots' Ennis and Vergil Ortiz Jr for a 'mega-fight' in the UK later this year.
Dobson has had plenty to say about Benn on social media, but this is a formidable challenge for the American who is unlikely to be capable of making the big step up.
While it wouldn't be a surprise to see Benn content to rack up the rounds again in total and complete control, he may also feel like producing an emphatic knockout to really make his presence felt back in the division.
