Live tonight from the MGM Grand Garden Arena in Las Vegas, Nevada, the UFC will present its last pay-per-view of the year, UFC 155: Dos Santos vs Velasquez 2. The last time these two met, Dos Santos gave Velasquez his first MMA defeat and also took away the UFC Heavyweight title on the first UFC on FOX show.

Weigh-ins were held yesterday afternoon at the MGM Grand Garden Arena, hosted as always by Joe Rogan with Dana White present. All fighters on the card made weight with Melvin Guillard having to cut weight twice in two weeks after he was supposed to fight in the TUF Finale but his opponent was sick.
