International Boxing Federation welterweight champion Simon Brown (32-1, 24 knockouts) has a new opponent for his Saturday night bout on the undercard of the Mike Tyson-Alex Stewart fight in Atlantic City. Ozzie O'Neal (14-9-2), from Youngstown, Ohio, replaces Roger Brown in the 10-round, non-title bout.

Roger Brown (11-13) did not withdraw from the bout, but was not approved by the New Jersey State Athletic Commission as an opponent, chief inspector Sylvester Cuyler said.

Roger Brown's "record was too poor to be fighting someone of the caliber of Simon Brown," Cuyler said yesterday. He added that as of yesterday O'Neal had not been approved by the commission, pending word from the Ohio Boxing Commission.

"It's just a formality, but we want to make sure O'Neal has no outstanding suspensions or anything like that," Cuyler said. "It looks pretty good to me, to be honest. The competition he's faced has been better {than Roger Brown's}."

Cuyler said he expected to hear from the Ohio commission by Wednesday.

O'Neal, 30, last fought Nov. 10, when he lost a 10-round decision to Eric Podolak in Erie, Pa. He fought to a six-round draw with Kato Wilson of New York at the Holiday Inn Crowne Plaza in Rockville Aug. 27. O'Neal has been knocked out in five of his last nine bouts.
