The Status of The WWE Champion
According to F4WOnline, The Rock is expected to be around until after Wrestlemania 29, and then he will be filming Hercules. Hercules is being filmed in Hungary and Croatia, so it is impossible for The Rock to work both at the same time.
It is unknown when exactly he will be back after that, but reports are saying that he is open to working Summerslam, especially since it is in Los Angeles. The Rock has confirmed that he will be working Wrestlemania 30.

Rey Mysterio was taken off television to work the injury angle played up by his attacks from Mark Henry. He is currently in Hawaii, and is scheduled to be back on the road with the crew this coming Monday.
