Former Ultimate Fighting Championship heavyweight champion Frank Mir will fight Justin McCully on July 5 in Las Vegas, sources close to both camps have confirmed. Bout agreements have been signed, adding the first heavyweight match-up to a card headlined by Quinton Jackson and Forrest Griffin.

In his last Octagon appearance, Mir took just 90 seconds to submit the heavily hyped Brock Lesnar by kneebar at UFC 81. The former champ has been slowly on the mend since a 2004 motorcycle accident brought a halt to his career, winning three of five fights since returning to competition. A win over McCully may put the Las Vegas-based heavyweight within striking distance of a title shot.

McCully, 8-3-2, has not fought since last April, where he won a unanimous decision victory over Antoni Hardonk at UFC Fight Night 9. He was scheduled to fight last September at UFC 77, but an elbow injury forced him off the card. The Team Punishment heavyweight will be facing one of his toughest tests in Mir.

Though the UFC has yet to confirm the bout, the fight is expected to be part of the pay-per-view broadcast.
