Will Rollins and Ambrose face off at Battleground?

On Raw, Ambrose was beaten down by Rollins, Kane and Orton and wasn't seen for the rest of the night. On Smackdown, Rollins sells the knee injury from Raw and says he won't be able to compete this Sunday. Obviously it's likely just a swerve to hype the match but COULD the WWE save the match for Summerslam to build anticipation even more? I'll be disappointedif I don't see it Sunday because it's the match I'm most looking forward to. Has this been done before?
