Cung Le put a serious exclamation point on the UFC’s debut in China, much to the delight of the crowd.

The South Vietnan born fighter knocked out UFC legend Rich Franklin with a looping right hand right on the chin in the very first round. Franklin, a heavy favorite, was out cold immediately and face planted to the canvas in the main event bout.

Le, 40, celebrated with a back flip afterward. It was his greatest performance in the UFC to date and an incredible way to promote his new movie with Russell Crowe and Lucy Liu, “The Man with the Iron Fists.”
