Former UFC welterweight champion Robbie Lawler was unsuccessful against Rafael dos Anjos last month, dropping a decision.

During the fight, Lawler suffered what has since been confirmed as a torn ACL along with other damage to his knee.

“The guy’s leg was destroyed,” UFC president Dana White disclosed during an interview with Yahoo Sports. “Okay? Blew his ACL and his meniscus and every other thing that’s in your knee out in like the third round. Wobbled over to the fence, laid against it, and asked dos Anjos to come in so that they could just bang it out. Robbie Lawler went to the fifth round.”

The 35-year-old Lawler (28-12) has gone just 1-2 over his last three, defeating Donald Cerrone via decision last July after dropping the belt to Tyron Woodley in 2016. Prior to that, “Ruthless” had picked up five consecutive wins, besting Carlos Condit, Rory MacDonald, Johny Hendricks, Matt Brown and Jake Ellenberger.

Lawler is likely looking at time on the sideline for much of 2018 with the injury. It’s possible that, depending on how long the rehab takes, that Lawler does not fight again until 2019.

After hearing that Lawler suffered the injury during their bout, dos Anjos offered his best wishes for a “speedy recovery.”
