Video: Watch UFC on FOX 12 headliner Robbie Lawler's clash with Bobby Voelker

Heading into Saturday’s UFC on FOX 12 headliner, Robbie Lawler is on a 4-1 run with three knockouts. Check out one of the more impressive performances from his recent body of work.

After making a triumphant return to the UFC in early 2013 and stopping Josh Koscheck, the Strikeforce vet was slated to fight Tarec Saffiedine, then Siyar Bahadurzada, and finally late replacement Bobby Voelker at UFC on FOX 8 in July 2013.

For Voelker, it was a step up in competition and opportunity to make some waves in the UFC welterweight division. But for Lawler, it proved to be an opportunity to add to his highlight reel.

Check out the full fight above.

And catch Lawler (23-10 MMA, 8-4 UFC) in action on Saturday, when he fights fellow contender Matt Brown (19-11 MMA, 12-5 UFC) in UFC on FOX 12's network-televised headliner at San Jose’s SAP Center. A shot at UFC welterweight champion Johny Hendricks is on the line.
