It's crazy that it's been six days since America changed forever with Undertaker losing in Wrestlemania (shivers). It may be time to get over it, because FINALLY, THE ROCK HAS COME BACK TO WRESTLING!
Actually, change "has" to "will possibly." It just doesn't sound as authoritative if it's a maybe.
Anyway, The Rock is currently considered a possibility to headline next year's Wrestlemania. He could be the one facing miracle worker Brock Lesnar or it could be Cesaro vs. Lesnar for the main event.
The Rock got injured in his loss against John Cena in Wrestlemania 29. He probably has a rematch clause in his contract in case he lost, so The Rock again being in the main event is very possible. Fast & Furious 7 is also scheduled to come out a little over a week after Wrestlemania 31 (March 29), so prepare for that Rock takeover.
