MMA fighter and expert grappler Jake Shields will make his return to Submission Underground after he defeated Chris Lytle in the inaugural event in July 2016.

In addition to Danis vs. Shields, the submission-only matches pull from some of the world's top jiu-jitsu black belts and will feature several matchups starring up-and-coming prodigies, UFC stars, and grappling veterans. The Submission Underground 4 card includes:

• ​Paulo Miyao vs. Urijah Faber

"It's awesome to see fighters return to the Submission Underground cage," Sonnen said. "When we started this event, we knew it would be something special and we're excited to continue to give fans the opportunity to see who are the best submission fighters in the world.

"Danis and Shields are two of the top fighters in professional grappling right now. As Submission Underground continues to gain momentum, we're thrilled to give UFC competitors and some of the top grapplers in the sport today a new arena to compete."
