We’re hearing that the current plan for the Vince McMahon/Shawn Michaels storyline is for Shawn to face none other than The Rock at Wrestlemania 22 in Chicago. In the storyline Vince will apparantly put up “big bucks” to bring back “Hollywood” Rock in an attempt to take out Michaels. Interestingly, you’ll remember them doing something VERY similar back in 2003 before No Way Out with The Rock coming back in to face Hogan. Due to the (fairly) detailed description of what the plan is we would assume rock has already been contrcted and has agreed to the match. We would not expect a long feud however, instead expect vince to feud with HBK and bring Rock in just a few weeks prior to wrestlemania. This would work out best for Rock who is beginning filming of a new movie around April time.

This also puts the rumoured Austin/Hogan match in major doubt as we are told WWE do not want to promote both austin/hogan and rock/michaels on the same card, so if this is the plan as we are hearing it is then it seems WWE must have given up on getting austin and hogan together at WM.

More as we get it.

webmistress comments: ok not to rain on anyone parade but I remember Rock saying he had no desire to work with Michaels whatsoever so I would like to see how this is gonna play out. I will keep you all posted when i get news
