Knockout of the week: Frankie Edgar takes out Gray Maynard

Frankie Edgar will head to Japan soon to defend his UFC lightweight belt against former WEC champ Ben Henderson at UFC 144. How about a little reminder of what Edgar did in his last bout?

His fourth-round knockout of Gray Maynard ended any question about who was the better fighter. With Henderson, he'll have to face a fight who has never been knocked out, and was submitted once in 2007. Who will take the belt home from Japan? Tell us in the comments or on Facebook.
