Earlier today, Cena was in Las Vegas as part of a promotional appearance for his new Fitness product campaign. This means he made the appearance, flew cross-country to Philadelphia for the match....and will now fly back to Vegas tomorrow for the WWE Network announcement.
For all the criticism some fans put upon John Cena, no one can deny that he puts WWE before all else in his life and has a work ethic that is beyond insane. This is why he's in the position he's in for WWE and will stay there...because he earns it.
In the dark match, Cena defeated WWE World Heavyweight champion Randy Orton by DQ. Mick Foley was advertised as guest referee, but did not appear.
