Jinkies! Champ Cris Cyborg had a masked grappling partner at UFC 222 workouts

LAS VEGAS – It didn’t quite match the drama of a “Scooby Doo” bad-guy unmasking, but UFC champion Cris Cyborg provided some fun with today’s open-workout grappling partner.

While working out for fans at today’s fan and media session in Las Vegas, the UFC 222 headliner hit the mat and rolled with a mystery masked man.

After a bit of grappling, Cyborg (19-1 MMA, 4-0 UFC), who meets challenger Yana Kunitskaya (10-3 MMA, 0-0 UFC) in Saturday’s pay-per-view main event at T-Mobile Arena, ripped of the mask to unveil – jinkies! – UFC Hall of Famer and friend B.J. Penn.

Check out the highlights, including the surprised crowd’s reaction to retired fan favorite Penn, above.

And catch Cyborg, the reigning UFC women’s featherweight champ, back in action on Saturday as she attempts her second title defense and 20th consecutive victory. She’s currently a massive favorite at the sports books.
