Brace Yourself for the Most Devastating Girlfight Knockout Punch You’ll Ever See

Here's a knockout so awesome we got a concussion just watching it.

Jinh Yu knocked out Darla Harris during the Sugar Creek Showdown last weekend in a bout that lasted 24 seconds -- yup, the same time an NBA team gets to shoot the ball. Watch Yu take down Harris with a 1-2 punch that's so intense Harris' grandkids will probably feel the pain until they're out of their teenage years.

Even more impressive? This was only Yu's second pro fight.
