-- WWE will turn back the clock this Monday on RAW as the program is being branded as an "old school" episode. Aside from the likely return of The Undertaker, the episode is being internally considered a throwaway show and undercard matches for WrestleMania will not start to take shape until at least the following week.
-- The official Facebook page of WWE announced last Thursday that WWE Champion Dwayne "The Rock" Johnson would be among those present for Extreme Rules at the Scottrade Center in St. Louis, Missouri on May 19. Johnson, however, noted that he will be in Europe filming MGM and Paramount Pictures' Hercules during this time frame.
Furthermore, the official website of the Scottrade Center, nor WWE.com, is advertising Johnson for the pay-per-view event.
