Hasim Rahman vs. Oleg Maskaev II, billed as America's Last Line of Defense, was a professional boxing match contested on 12 August 2006, for the WBC heavyweight championship.

[2] Since the retirement of Vitali Klitschko elevated him to a two time Heavyweight Champion, Hasim Rahman had made one defence, a majority draw against James Toney.

Maskaev was consistently warned by referee Jay Nady about excessive holding, which the ringside HBO commentators, which included Lennox Lewis, felt was unwarranted and one-sided.

Maskaev landed a flurry of blows prompting the referee to wave off the bout in order to save Rahman from further punishment.

Two of the three judges Jerry Roth and Glenn Trowbridge had Maskaev ahead with scores of 104–105 & 103–106, while Anek Hongtongkam had it for Rahman 106–103.
