According to linesmaker Nick Kalikas of BetonFighting.com, it's number one contender Junior dos Santos, who was immediately inserted as the -125 favorite in his still unscheduled upcoming bout against Cain Velasquez.
The heavyweight champion stands as the slight underdog at -105.
Anyone jumping on this line with wallets wide open? Or do you expect a dramatic shift as we get closer and closer to fight night, whenever that may be?
There are obviously a few factors at play here.
Dos Santos just blasted past Shane Carwin, emphatically putting a stamp on his status as the second best heavyweight in the division with a convincing win at UFC 131.
Add that with Velasquez coming off a long layoff and a serious shoulder injury, which required even more serious surgery, and it's easy to see why the oddsmakers have inserted "Cigano" as the early favorite.
The lines will shift and move as the betting dictates, of course, but the consensus opinion seems to be that they'll hold steady right where they are now.
