UFC welterweight Robbie Lawler will face Matt Brown in the main event of UFC on Fox 12 next week in San Jose.

It's one of the biggest fights of Lawler's career. If he scores a win over the surging Brown, he'll put himself back into a title rematch with welterweight champion Johny Hendricks.

Needless to say, Lawler has a lot on the line in this fight. But over the past few months, he has spent his free time keeping the employees in Bleacher Report's San Francisco office in line. Lawler served as B/R's office enforcer; let's just say you don't want to act like a fool when "Ruthless" is around!

Check out the video above, and always remember: Get back to work!
