Austin Theory was knocked out by a non-WWE talent on the latest episode of SmackDown. The person in question is undefeated boxer Terence Crawford.

Last week on the blue brand, Crawford helped Cody Rhodes by handing him a steel chair after he was confronted and attacked by A-Town Down Under. The American Nightmare used it to fend off the former WWE Tag Team Champions.

On this week's WWE SmackDown, Austin Theory and Grayson Waller called out Terence Crawford during an in-ring segment. After the latter came out, the Aussie star told him that he disrespected them by helping Cody Rhodes last week. Waller told the boxer to apologize to them.

They wanted an apology for two reasons, because he helped Cody, and because he thought that he deserved to be in the ring with A-Town Down Under. Grayson Waller then told Terence Crawford that if he took one more step toward him, Austin Theory would knock him out.

It seemed like Theory wasn't expecting his tag team partner to say that, as he had a surprised look on his face. Even as he took a step forward, Terence Crawford knocked him out anyway. Grayson Waller exited the ring and left his partner lying in pain on the mat.
