The Kentucky Boxing and Wrestling Authority had issued WWE nine violations of state law for various occurrences, mostly concerning the use of blood, at the Backlash PPV. Prior to the show, the WWE was warned against the use of blood. WWE asked for allowance of special usage of blood and/or allowance to stop a match in the case of accidental bleeding, the latter of which is in according with the commission's rules, which the commission denied. WWE was fined $3,250 and given a 24-month probationary period by the Boxing and Wrestling Authority.
