UFC bantamweight Jacqueline Cavalcanti sent her male sparring partner tumbling to the canvas after landing a perfectly timed knee.
The Brazilian-born Portuguese fighter is yet to score a finish under MMA's premier promotion.
All five (5-0) of her UFC victories have come over the distance, but that doesn't mean she can't generate a lot of force with her strikes.
In a video uploaded to social media, the 28-year-old can be seen moving around the cage with a significantly bigger man.
Cavalcanti throws a jab and a lead hook before landing a vicious knee as her sparring partner shoots in for a takedown.
The shot leaves the man flat on his back, and while he shakes his head and puts his hand up, he is clearly hurt.
A coach, left in disbelief by what he had just witnessed, asks Cavalcanti:
