Evander Holyfield vs. John Ruiz, billed as Justice, was a professional boxing match contested on August 12, 2000 for the vacant WBA heavyweight championship.

Ruiz's promoter Don King challenged the decision in court and a clause was found in Lewis' contract that stated the winner of the Holyfield–Lewis fight would first defend his titles against the WBA's number one contender.

The co feature of the bout was set to be a mandatory defence for WBA welterweight champion James Page against Andrew Lewis, however it was called off at a few days notice after a dispute over the purse bid.

[4] Ruiz was aggressive throughout the fight landing many effective jabs, and except for late in the third round, he was never really in any serious trouble from Holyfield.

Judges Duane Ford and Dave Moretti scored the fight 114–113, while Judge Fernando Viso scored it 116–112 giving Evander Holyfield victory by unanimous decision to become the first boxer in history to be the World Heavyweight Champion four times.
