On March 30, 2007, in their hometown of Detroit, Shelley and Sabin made their ROH debut as a team under the name The Murder City Machine Guns by challenging and then attacking Jay Briscoe after he and his brother Mark, who had injured himself during the match, had won back the ROH World Tag Team Championship from Naruki Doi and Shingo. On April 28 in Chicago, IL, at "Good Times, Great Memories" The Briscoe Brothers successfully defended their tag team title against Shelley and Sabin. After the event TNA pulled all of their wrestlers from any upcoming ROH shows.
