5 best 'undersized' UFC fighters

#3 Demetrious Johnson

Demetrious Johnson v Wilson Reis

In 2011, Demetrious Johnson became the inaugural UFC flyweight champion. His title reign saw 11 defenses, making him one of the greatest pound-for-pound fighters in MMA.

At 5'3", he is one of the shortest male fighters to compete in the promotion. Notably, the shortest male fighter in the company's history is Hector Sandoval, who is 5'2".

Johnson flaunts an outstanding resume of 30 wins, 4 losses, and 1 draw. After losing the flyweight championship to Henry Cejudo in 2018, he went on to fight in One Championship. He gained the vacant bantamweight title within that promotion in 2019, but then lost it to Adriano Moraes in 2021. It was the first knockout loss of Johnson's career.
