Alistair Overeem entered the UFC with a ton of momentum and he didn’t disappoint.

Overeem (45-18 MMA, 10-7 UFC) faced former UFC heavyweight champion Brock Lesnar at UFC 141, and the “Demolition Man,” who had finished 10 of his last 11, showed no mercy.

After stuffing Lesnar’s first takedown attempt, Overeem cornered Lesnar and threw several big knees to the body in the clinch that had Lesnar wincing in pain. Shortly after, he went right back to the body again and connected with a huge liver kick that winded Lesnar as the former champion dropped him to the canvas. A few powerful punches later, including one vicious body shot, and the fight was stopped, as Overeem picked up his highest-profile UFC win to date.

Overeem went on to have several ups and downs in his UFC career, including a failed attempt to capture the UFC heavyweight title. More recently, after racking up two straight first-round finishes over Sergei Pavlovich and Aleksei Oleinik, Overeem was stopped by Jairzinho Rozenstruik in his last outing in a fight that he appeared to have dominated.

Now “The Reem” will look to rebound once again when he takes on Walt Harris in the UFC on ESPN 8 headliner this Saturday.

But before he faces Harris, relive Overeem’s memorable finish of Lesnar in the video above.

UFC on ESPN 8 takes place Saturday at VyStar Veterans Memorial Arena in Jacksonville, Fla. The card airs on ESPN and streams on ESPN+.
