Michael Bisping visited the Wild Card's gym in Hollywood, CA to touch up on his stand-up for this upcoming fight against Mark Munoz. Apparently Bisping was going really hard in the ring and disrespecting his sparring partner, so a coach sent in a professional boxer to 'spar' with Bisping. Within minutes, this professional boxer knocked out Bisping as payback for disrespecting the Wild Card gym.
Best rumor of the bunch. Wish I was there to see it.
