As previously reported, The Big Show returned to take John Cena's place in the main event of house shows over the weekend due to Cena's surgery. He will also replace Cena tonight in a dark match against Punk.
Cena will appear on RAW tonight in Albany, NY to talk about his status and WWE will make an announcement as to who Punk will face at Hell in a Cell.
We can confirm that The Big Show is backstage at RAW and will likely return tonight. As noted, he'll be in the dark match but should appear live as well unless they hold it off until SmackDown.
