In an interview with Michael David Smith on Fanhouse, Coker confirms the signing of Werdum, but also states that a hw title fight with Alistair Overeem is not a lock:

Will Alistair Overeem fight on June 6?
We're trying to work it out. It's not guaranteed, but we'll try to put it together.

Who would his opponent be?
That hasn't been determined yet. 

Did you just sign Fabricio Werdum?
Yeah, but that's not a fight necessarily we feel we'd have to do first.

Frankly, aside from Fabricio Werdum I'm not sure you have any heavyweights who could give Alistair much of a test.
Well, there are some other free agents out there, and guys fighting with other companies who aren't exclusive. So we'll explore those options before we make the announcement of who he's fighting. 

Frankly, the only other HW Free Agents I can think of are Roy Nelson, and I guess the DREAM HWs would be available in America(CroCop, Schlit, Kharitinov). I don't know for sure if Rothwell is exclusive with Adrenaline either. Saying that, none of them are really more deserving than Werdum. Nelson would be a nice depth signing as a future contender, but the rest of the current Free Agent crop is underwhelming.
