Roy Jones Jr. withdraws from fight

Roy Jones Jr., citing a hand injury, withdrew Wednesday from his scheduled Oct. 7 cruiserweight fight with Danny Santiago.

Square Ring Promotions, Jones' company, announced it was postponing the entire card, which was to have featured boxing matches and mixed martial arts bouts at the Pensacola Civic Center in Pensacola, Fla., Jones' hometown.

"Roy's manager, McGee Wright, informed me [Wednesday] that Roy injured his left hand while sparring on Saturday and that on Monday, he went to the doctor and X-rays were taken," said John Wirt, CEO of Square Ring Promotions. "While the X-rays do not show a fracture, his hand is swollen and continues to bother him to such an extent that we have no choice but to postpone the fight."

Jones, the former pound-for-pound king and four-division champion, has lost his last two fights, a first-round knockout to Danny Green in December in Australia followed by a one-sided decision loss in a rematch with longtime rival Bernard Hopkins.

Many have called for Jones, 41, to retire after poor performances in recent years. However, Jones plans to reschedule the bout.

"At this point, we are planning on rescheduling the fight and will make an announcement regarding the new date as soon as possible," Wirt said.

Although the cruiserweight limit is 200 pounds, Jones (54-7, 40 KOs) and Santiago (31-4-1, 19 KOs) were scheduled to meet at a contract weight of 185.

Santiago, 31, of Ocala, Fla., has won two fights in a row on the Florida club circuit. He lost his two most notable fights in a row. Zsolt Erdei stopped him in the eighth round of a light heavyweight world title bout in 2007 and, later that year, former light heavyweight champ Antonio Tarver, knocked him out in the fourth round.

Tarver, of course, has a lot of history with Jones. He lost his first fight to Jones, but then beat him easily in their second and third fights, including a shocking second-round knockout in their 2004 light heavyweight championship rematch.

Square Ring had not secured a television deal for Jones-Santiago.
