Cain Velasquez knocked down Antonio "Bigfoot" Silva with a combination and finished him on the ground 1:21 into the first round Saturday night, briskly defending his heavyweight title at UFC 160.

Former heavyweight champion Junior Dos Santos also stopped Mark Hunt on a spinning kick to the head with 42 seconds left in the third round at the MGM Grand Garden Arena, likely setting up a third fight between Dos Santos and Velasquez in the near future.

Velasquez (12-1) made his first successful title defense in style, rocking Silva in the opening minute before mercilessly punishing him on the ground.

Silva (18-5) was a heavy underdog in the UFC's usual Memorial Day weekend show in its hometown.
