HBO had the right to his tune upoverseas as well but they ended up passing on the Adama fight because of the time delay and there was no HBO fight later that evening to replay it on.
Anyways, Golovkin has an HBO contract on April 26th. If Golovkin wants another tune up after that but before his next HBO date in September overseas and Lara is willing to fight for about $50,000 with no network good luck with that. The man behind Lara's twitter is his manager, DeCubas jr., not Lara. His goal is to make him money, thus the recent calling out of Mayweather, GGG, Canelo, Andrade and other guys. I highly doubt Al Haymon and DeCubas would want Lara fighting a MW overseas with no network backing for peanuts. They didn't even send an offer to team GGG, all DeCubas said was have HBO send Al Haymon an offer.
