TNA was planning to run a major feud between the Motor City Machineguns and Generation Me (the former Young Bucks), who had a great match on the January 4, 2010 Impact.
However there have been injury issues on the MCMG side, most notably Alex Shelley, who reportedly has some neck issues that might keep him out of action for a while. This combined with Chris Sabin’s stinger from Impact a few months back, and the feud has been put on hold until TNA is sure they can run the matches without further injuries.
