Ruthless Robbie Lawler lays out Bobby Voelker in this Killer Finish from UFC on FOX: Johnson vs. Moraga. Lawler shows off some dynamic striking in this bout. The patented left hand is there, but Robbie also lands a jump knee and a few head kicks. This was his second fight back in the UFC — and his second straight win at the time. Lawler’s win over Voelker came just a few months after his return to the UFC, a glorious first round knockout of Josh Koscheck at UFC 157.
