Why not make July 18th a regular HBO fight for Marquez?

They already have the date and saved money by not doing Klitschko-Chagaev. Maybe put on like Marquez vs Khan. The khan fight was just cancelled and they could do it in Britain. Would be a massive fight there and solid in the US. y'know what, I wouldn't mind this because then marquez could get a tune up for 144 lbs.

Because it's too little notice and Warren doesn't want Khan to get knocked out again so soon. HBO wants to save their budget too, they've supposedly used up most of their budget for big fights in the first half of the year.
