Antonio Silva scores a shocking upset victory over Alistair Overeem at last night's (Sat., Feb. 2, 2013) UFC 156: "Aldo vs. Edgar" event at the Mandalay Bay Events Center in Las Vegas, Nevada, knocking the Dutchman out in the third round of their heavyweight tilt after getting thrown around like a rag doll for the first two. "The Reem" talked a big game heading into the bout and it looked like he was going to back it up too, but "Bigfoot" found an opening at the start of the final frame and made the most of it, blitzing his foe and unleashing a vicious flurry of powerful shots that would put any man down. Just watch the video above to see what I mean. Nasty, right?
