Regardless of how Matthysse stacks up in p4p punching power, I was impressed by that first knockdown of Peterson. Watching it live, at first I thought he had missed with that wide left hook.... and then Peterson inexplicably tripped and fell. So I was puzzled when it was scored a knockdown. Then I saw the replay and saw how the punch clipped Peterson just above the temple area. As Lamont moved away, in a delayed reaction his feet lost coordination... and he tripped and fell in the corner.

Amazing. Had that punch landed more solidly... or on the chin... there would've been no standing 8-count.
