Watch: Cyborg spars with 2-time Olympic boxing champ Shields

Cris Cyborg is bringing in the best to prepare for her upcoming UFC title fight.

Ahead of a bout at UFC 214 against Megan Anderson for the vacant women's featherweight championship, Cyborg enlisted the help of two-time Olympic gold medalist and undefeated pro boxer Claressa Shields. "T-Rex" posted a video of herself and Cyborg putting in work, and while Shields has an obvious advantage, her MMA counterpart doesn't back down from the challenge.

As if Cyborg wasn't already one of the most feared strikers in the Octagon, now opponents can look forward to her hands being even deadlier.
