I'm hearing Overeem signed with the UFC yesterday, officially.
I have no source other than some Dutch guy on another forum I visit. The only reason I'm giving it credence is because, bizarrely he accurately predicted that Overeem would only fight 2 more times for SF(even though it was technically one, he was scheduled for a second)
Not sure if true, but that's what I'm hearing.
It was also revealed on a dutch news site, there was something with his management or whatever that led to strong believement about the situation as well. When Ariel asked Dana if Overeem had signed the contract, Dana replied "not yet".
I think it's like 80% sure his in the UFC now.
