AUSTIN, TX -- March 27, 2017 -- Today, FloSports, the innovator in live digital sports and original content, announced the official main card for Submission Underground 4 featuring Dillon Danis and Jake Shields as the headline fighters for the May 14 live event in Portland, Ore. The submission-only grappling competition, co-presented by FloSports and Chael Sonnen, will be live streamed to an international audience exclusively on FloGrappling.com starting at 3:00 p.m. PST.

Hosted at Portland's Roseland Theater, Submission Underground 4 features the world's most competitive grapplers going toe-to-toe in a cage. In his second Submission Underground competition, headline fighter Dillon Danis will look to defend his title after beating AJ Agazarm in OT in Submission Underground 3. 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 currently includes:

• Paulo Miyao vs. Urijah Faber
• Michael Perez vs. Nathan Orchard
• John Combs vs. Gilbert Burns

"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."
