As with anything FEG-related, it is best to approach anything you hear like a one night stand; carefully, with protection, and to do your best to forget about it the next morning. Our friends at NightmareOfBattle learned that the Lashley vs. Overeem bout is indeed "off" -- as if it was ever truly on.
From what we are hearing currently, Lashley's management turned down the fight due to not having enough time to prepare for a bout of that magnitude, which all-in-all is a very smart move. Liver Kick is still waiting to hear back from Alistair Overeem's management as to what the future plans are, but we do know that Bobby Lashley will not be the opponent, nor will Satoshi Ishii, who is fighting Jerome Le Banner instead.
The current rumor is that Golden Glory fighters will clash in the fight that fans across the world were waiting for at this year's World Grand Prix; Alistair Overeem vs. Semmy Schilt. No word on the validity of this rumor, or if it would be DREAM or K-1 rules, but we should have more details within the next few days.
