Heard a lot of rumors about this, and did see a link that supposedly has confirmation directly from Dana but couldn't get the page to load.
With that said;
Gilbert Melendez and Anthony Pettis
If this is true, it means two things aren't happening:
1) Pettis/Aldo isn't happening, at least not yet.
2) Melendez isn't leaving for Bellator, even though he signed a contract with them (which the UFC was allowed to match). That one is actually kind of funny, because it means Dana just played Rebney so bad and made him look like a tool in front of the entire MMA world. All of Rebneys trash talk about the UFC lately, and his own pride in thinking he was about to get on a roll stealing UFC talent really backfired this time if this is true.
