UFC 166 fight card: Velasquez vs. Dos Santos 3

UFC 166 has started to round out a bit, and we've already got the looks of an amazing card. The main event will be the third fight between Cain Velasquez and Junior dos Santos for the UFC heavyweight title, but there's so much more than that. Daniel Cormier will face off with the re-signed Roy Nelson in another heavyweight bout set for the co-main event. And a bunch of other already-announced bouts should make up the main card.

Former Bellator middleweight champ Hector Lombard will make his welterweight debut against former Strikeforce champ Nate Marquardt. Another former SF champ, Gilbert Melendez, will meet TUF 1 winner Diego Sanchez. And a great middleweight bout between Tim Boetsch and Luke Rockhold was just added today.
