It might just be in you choice of words, but Boxrec don't decide whether it's official. They are just present information and have changed their website to reflect what we all know already. They were risking losing a lot of credibility if they didn't do this, but they claim they were leaving it as a NC until the true status of the fight was determined, if that's true then that's fair enough.
They say the unsanctioned reference wil disappear once they receive the commision report from the LBF. Sounds fair enough.
Well if boxrec 'make it official'; I am officially calling it a 'No Contest'. Everything that site as done thus far in the 'Haye/Chisora saga', has been about face, from the 'general consensus'.
