Antonio Silva scores major UFC 156 upset with knockout of Alistair Overeem

Antonio Silva patiently fought Alistair Overeem at UFC 156, and then pulled off the biggest upset of the young year with a knockout win.

The first round was more clinch-filled than was expected, but Overeem definitely got his licks in. He used leg kicks and punches as well as fantastic movement to hold off Silva. Overeem also landed 13 body shots in the first round.

Overeem went a different route in the second round, taking down Silva early in the round. After Overeem controlled and beat up Silva for much of the round, they were stood up and they finally started throwing at each other.

In the third round, Silva became aggressive and Overeem stood right in front of "Big Foot." Silva landed a bevy of punches that first wobbled Overeem, and then sent him to the ground. Silva had to be pulled back by referee Herb Dean. The fight was stopped 25 seconds into the final round.

This was Overeem's first fight since beating Brock Lesnar late in 2011. Since then, Overeem was given the title shot, and then lost it after pre-fight tests caused him to be suspended in Nevada. He was hoping for a title shot immediately upon his suspension, but had to beat Silva first. That title shot is not meant to be.
