WASHINGTON – Emotions were riding high right from the get-go at the Verizon Center as John Cena and Brock Lesnar exchanged punches in an all-out brawl, but it was the self-proclaimed "War Machine" who landed the last blow of the night. Also on Raw SuperShow, WWE Champion CM Punk suffered another disturbing attack at the hands of Chris Jericho, and Kane took out his anger on one of The Three Stooges!

Raw GM John Laurinaitis came out to introduce Brock Lesnar, proclaiming that he's the new face ofWWE, and announced that Lesnar will face Cena at Extreme Rules on April 29. (MATCH PREVIEW)

Lesnar thanked Laurinaitis for having the wisdom to bring "legitimacy" back to WWE, but that statement didn't sit right with John Cena, who quickly charged out to the ring for a heated staredown with the very man who laid him out with a brutal F-5 the previous week on Raw.

The Cenation leader proceeded to slap Brock in the face, triggering a near-uncontrollable brawl. Pandemonium broke loose and the WWE locker room emptied as over a dozen Superstars and Officials tried to pull the two competitors off each other. It took repeated efforts to stop Brock and Cena from pounding each other to bits as the Verizon Center erupted. Cena suffered a nasty bloodied lip as a result of the wild melee with Lesnar. (PHOTOS)
