Back in 2010, heavyweight Fabricio Werdum entered the Strikeforce cage in what was the biggest fight of his career.

He was set to take on MMA legend, Fedor Emelianenko, in the night’s main event. Fedor had not lost in 10 years and was considered to be unbeatable. Werdum was on a two fight win streak, but by far considered the massive underdog.

Then, he won.

The fight went to the ground, with Werdum on the bottom, and from there it didn’t take long for him to lock up an armbar and force Fedor to tap.
