Hungary's Zsolt Erdei will fight former super middleweight titlist Byron Mitchell on June 4, Erdei promoter Lou DiBella told ESPN.com.
Erdei, a former light heavyweight titlist who vacated his belt to move up, won a cruiserweight title and then returned to 175 pounds.
The scheduled 10-round bout will take place on the undercard of the Super Six World Boxing Classic semifinal match between super middleweight titlist Carl Froch and Glen Johnson at the Adrian Philips Ballroom at Boardwalk Hall in Atlantic City, N.J.
It will be Erdei's second straight bout in the United States, both since he signed with DiBella. Erdei also fought in Atlantic City on the November undercard of middleweight champ Sergio Martinez's second-round knockout of Paul Williams in their rematch. Erdei drew a large contingent of Hungarian fans who waived flags, chanted and sang throughout his lopsided eight-round decision win against Samson Onyango.
"Zsolt needs to fight and stay active and stay in the consciousness of fans, plus he will be on the international broadcast," DiBella said. "And last time he fought in Atlantic City, he brought a big crowd. So the idea is to get him a fight against a recognizable opponent, which Mitchell is, and wait our turn for something bigger."
DiBella said Erdei (32-0, 17 KOs) is the mandatory challenger for the winner of the May 21 bout between titleholder Jürgen Brahmer and Nathan Cleverly.
"We're also in position to fight an eliminator in another organization after June 4, so we just have to keep him active and in front of people and he will get a big fight," DiBella said.
Mitchell (28-7-1, 21 KOs) has dropped back-to-back fights.
Allan Green, the former super middleweight contender, is also slated to fight on the undercard in a scheduled eight-round light heavyweight bout against an opponent to be determined.
Green (29-3, 20 KOs) was a replacement fighter in the Super Six tournament. He came aboard for Group Stage 2, where titleholder Andre Ward rolled to a shutout decision against him in June. In Group Stage 3, Green was knocked out in the eighth round by Johnson in November and has not fought since.
