Invicta FC 13 is going down tonight in Las Vegas, and is airing live on Fight Pass. In one of the early prelim bouts, a good friend of UFC women's bantamweight champion Ronda Rousey was competing, but like her last outing, things didn't go too well.
Marina Shafir, judo practitioner and member of the "Four Horsewomen", was facing off with Amber Leibrock in a featherweight bout. Leibrock, who was making her pro MMA debut, managed to put Shafir down with strikes in just 37 seconds. Check out the Tweet:
