ATLANTIC CITY, N.J., Dec. 13 (UPI) -- Eight titles will be on the line on Saturday night at Boardwalk Hall in Atlantic City, N.J.
Among the bouts will be the undisputed middleweight and welterweight straps.
Bernard Hopkins (42-2-1, 31 KOs), fighting for only the second time this year, takes on former WBA middleweight champion William Joppy (34-2-1, 25 KOs).
Hopkins, 38, became the first undisputed middleweight champion in 14 years, when he posted a TKO over Felix Trinidad in September 2001.
Joppy has won two fights since getting stopped in the fifth round by Trinidad in May 2001.
Also, Ricardo Mayorga (26-3-1, 22 KOs), who holds the WBA and WBC welterweight belts, will face IBF champion Cory Spinks (31-2, 11 KOs); Brooklyn native Zab Judah (29-1, 21 KOs) defends his WBO belt against Jaime Rangel; and a pair of former champions will square off for the interim WBA heavyweight title when Hasim Rahman (35-4-1, 29 KOs) takes on John Ruiz (38-5-1, 27 KOs).
The winner will become the mandatory challenger to Roy Jones Jr.
