According to Jason Powell at ProWrestling.net, Jerry Lynn has injured his back and pulled out of tomorrow night's PPV main event against Rob Van Dam as well as his weekend indy booking. TNA learned of the cancellation within the last day and as of this posting, they haven't made any announcements about it. No word yet as to the new main event. Powell doesn't think that Sabu as a replacement (in a perfect world the best sub on paper) is a good idea since he's pretty wrecked these days. 2 Cold Scorpio is believed to be working the show and could fit in well for the type of main event they were hoping for.
