A federal judge on Wednesday temporarily blocked the sale of a dozen items from Evander Holyfield's boxing career during an upcoming auction of hundreds of personal items and memorabilia amassed by the former heavyweight champion.

The restricted items include Holyfield's robes from his first fight with Mike Tyson and his Olympic bronze medal. Holyfield had sought to limit the sale of 20 items during an auction on Nov. 30 that is being organized by Julien's Auctions and will still feature several robes and other gear Holyfield wore during his fighting career.

Holyfield faces irreparable harm if the items are sold, U.S. District Court Judge Christina A. Snyder ruled, but the former boxer may have to post a bond to keep the items from being sold as he continues to argue his case that the items should be returned. The exact amount will be determined later.
