FRANKFURT, Germany — Evander Holyfield has been offered a fight with WBA heavyweight champion Nikolai Valuev in December.

Holyfield, a former heavyweight champ who turns 46 later this month, has not fought since losing an unanimous decision to Sultan Ibragimov, then WBO champion, a year ago.

"Yes, we are in negotiations with Evander Holyfield," Sauerland Event managing director Chris Meyer said Thursday. "We have made him an offer, but nothing has been signed yet."

Should the fight happen, it likely will be staged in either Switzerland or Germany, he said.

The 7-foot, 300-pound Valuev (49-1, 34 KOs) won an unanimous decision over John Ruiz in August to regain the WBA title.

A four-time heavyweight champion, Holyfield would become the oldest fighter to win the crown if the fight goes ahead and he defeats Valuev.
