The "shoot-style" fights featured one referee in the ring while two competitors went at it in MMA or street style fights, but they were worked just like WWE matches always are. The segments featured WWE Superstars Dolph Ziggler, The Viking Raiders, and The Hurt Business (who later announced they would be taking things over).
There were numerous other indie talents involved in the segment, which @LocalCompWWE ran through in a series of tweets.
The first fight introduced by Shane McMahone was between Mikey Spandex and Dante Marquis Carter of Task Force. In the next segment, Shane McMahon introduced Dabba-Kato (fka NXT's Babatunde) who wrestled Kai Douglas (WWN referee), Chico Adams was also in the scene.
Erik of The Viking Raiders faced "Upgrade" Mike Reed in their fight. In the segment with The Hurt Business, Ariel Dominguez was tossed around by the stable. Others in the crowd during RAW Underground: Marina Tucker, Sofia Castillo, and Vinny Mac.
