The Great American Bash PPV this Sunday is obviously going to need restructuring given Mark Henry's injury and Batista's lack of opponent.
Dave Meltzer reports that Batista may be added to the Mysterio vs. King Booker title match to make it a three-way, which will also mean the rest of the card will remain unchanged.
There is no heel on SmackDown right now to challenge Batista and it wouldn't make sense for either Edge or Big Show to appear on the PPV as Batista wouldn't be winning either title anyway.
