No chance of a match, and I doubt there's even a chance of him showing up in any capacity. Triple H doesn't seem to like him and said he doesn't deserve to be in the Hall of Fame (An absolutely absurd statement because based on WWE's own parameters, Goldberg should be in there more than Triple H). The only thing The Rock is going to do is what they've been building, involvement in Cena vs Miz, and hosting obviously, which means backstage segments which plenty of people. We can guess the likely people, Austin obviously, Alberto Del Rio just so they can do the predictable "My name is Alberto Del R....it doesn't matter what your name is!" bit, etc.
