Cain Velasquez's five-round demolition of Junior dos Santos on Dec. 29 won him the UFC heavyweight title and earned him a return trip into the Yahoo! Sports Top 10.

Velasquez checked into the poll at No. 6 in the January rankings after his impressive victory over dos Santos.

Demetrious Johnson was the beneficiary of a high-profile win, jumping up two spots from No. 9 to No. 7 after defeating John Dodson in an exciting flyweight title fight on Fox.

Lightweight champion Benson Henderson jumped up a spot from No. 6 to No. 5, replacing dos Santos, who fell out of the Top 10. Frankie Edgar slipped from No. 7 to No. 8 and Gilbert Melendez dropped from No. 8 to No. 9 to accommodate Johnson's move upward.
