Chael Sonnen has many roles in the combat sports world. On Sunday night, he was promoter and emcee … and event security.At Sonnen’s Submission Underground 6 event in Portland, he was in the cage interviewing Jake Shields after Shields’ victory over Gilbert Burns in the grappling event. Sonnen asked Shields who he’d like to meet next under the Submission Underground banner. That’s when things went a little sideways. After Shields mentioned names like Jon Jones and the Nogueira brothers, he called out A.J. Agazarm, another jiu-jitsu black belt he has known beef with. Agazarm entered the cage, and though Sonnen got between them Shields still managed to get a few swings off. When Sonnen tried to get Agazarm away from the potential fracas while other personnel dealt with Shields, Shields threw a right slap that appeared to hit Sonnen. Once Agazarm was out of the cage, Shields took the mic from Sonnen and delivered some … well, trash talk, is what we’d presumably call it though it left a little to be desired, perhaps. Shields called Agazarm a “(expletive) clown” and said he’d be easy work for him. So it looks like that’s a grappling bout that makes a lot of sense down the road. For now, though, check out the video above to see the whole ordeal.The Blue Corner is MMAjunkie‘s official blog and is edited by Mike Bohn.
