F4Wonline.com reports current plans are to have The Rock versus Brock Lesnar at SummerSlam.
Apparently there was once discussion about doing the match for WrestleMania 29. The thought process was to get the match between the two stars while WWE knew they had Lesnar under contract. Now that Lesnar is signed for another two years, WWE is looking at having the match in the summer.
Plans for the two to meet at WrestleMania 29 also got scrapped rather quickly as WWE really wanted to have The Rock involved in the WWE title picture. Also, Lesnar's schedule of being used was an obstacle as the company felt the match would have been rushed and not made much sense.
