Demetrius Andrade, who is due back in the ring on Oct. 21 in the first fight of a newly-signed three-fight contract with HBO – which has not been formally announced yet -- now has an opponent for the middleweight bout. Terms have been agreed to for Andrade to face Alantez Fox (23-0-1, 11 KOs), a 25-year-old prospect from Forestville, Maryland, a source with knowledge of the deal told ESPN. Fox, who like Andrade is moving up to middleweight for the fight, will be taking a gargantuan step up in the level of his opposition. Andrade (24-0, 16 KOs), 29, of Providence, Rhode Island, who owns a secondary junior middleweight title but is likely going to 160 pounds to stay, and Fox will fight on a “Boxing After Dark” card (10:05 p.m. ET/PT) headlined by Jezreel Corrales’ junior lightweight title defense against Alberto Machado at the Turning Stone Resort Casino in Verona, New York.
