Edison Miranda and Allan Green, two former contenders looking to get back into the title picture, will return in separate fights on the undercard of super middleweight titlist Carl Froch's defense against Glen Johnson in the Super Six World Boxing Classic semifinals June 4 in Atlantic City, N.J.
Miranda (33-5, 29 KOs) and Green (29-3, 20 KOs), who have both fought for super middleweight world titles, are moving up to light heavyweight.
Miranda, who had a number of exciting fights and scored plenty of big knockouts, has not fought since being stopped in the third round by super middleweight titlist Lucian Bute in April 2010. He returns in an eight-rounder against an opponent to be determined.
"I'd like to get him in the mix and make some money," Warriors Boxing promoter Leon Margules said. "Edison is a very exciting fighter. He adds a lot to the game of boxing. If he comes back and looks good, he can still stir it up and be a factor."
Green is scheduled for an eight-rounder against journeyman Dhafir Smith (24-20-7, 4 KOs), who outpointed former super middleweight titlist Jeff Lacy in a big upset in December.
Green talked a big game but was a massive disappointment when he was brought into Showtime's Super Six tournament as a replacement for former middleweight champion Jermain Taylor, who dropped out after suffering a brutal knockout to Arthur Abraham in their Group Stage 1 bout.
Green, who has lost two fights in a row in the Super Six, was shut out challenging titleholder Andre Ward in June 2010 and then knocked out in the eighth round by Johnson in November.
In a previously announced undercard fight, former light heavyweight titlist Zsolt Erdei (32-0, 17 KOs) will face former super middleweight titlist Byron Mitchell (28-7-1, 21 KOs) in a scheduled 10-rounder. Erdei looms as the mandatory challenger for the May 21 bout between light heavyweight titlist Jürgen Brahmer and Nathan Cleverly.
