A lot of fighters are currently signed to the UFC roster but who hits the hardest? Chael Sonnen and Kenny Florian weighed in and the answer might surprise you.

During a recent "UFC Tonight" broadcast, hosts Kenny Florian & Chael Sonnen, discussed this very topic.

Some of the fighters mentioned were Dan Henderson, Mark Hunt, Johny Hendricks, Robbie Lawler & BJ Penn, but ultimately this is what the guys had to say:

UFC Tonight host Host Kenny Florian on who's the hardest puncher in the UFC:

"I'd say Junior dos Santos. Not only is he a heavyweight and has the power, but he also has the speed. If he catches you, he'll knock you out."

Chael Sonnen on the hardest puncher in the UFC:

"I'd have to go with Vitor Belfort. He has the speed and accuracy and when he hits you, he's looking to knock you out."
