The early plans for Triple H vs. Brock Lesnar at WrestleMania 29 will be for there to be an MMA stipulation. The match is not expected to be contested under MMA rules but that could change. As of Monday night's RAW, no stipulation had been decided upon but three or four different scenarios were being discussed. They'll likely come to some sort of conclusion this week and it'll be announced next week on RAW when Triple H returns.
At Tuesday's WWE SmackDown tapings in Fort Wayne, Indiana, The Shield vs. Ryback, Randy Orton and Sheamus was announced for WrestleMania 29. The Big Show may end up replacing Ryback in the match. Mark Henry vs. Ryback is still rumored. We'll see.
