– WrestleZone reports that John Cena may not be back in for SummerSlam following getting surgery on the broken nose he suffered on Monday. The site says that sources close to the situation say that SumerSlam would be the earliest he can return to the ring and that he wouldn’t be fully healed if he is back by then.

The site adds that there is some debate over whether to book him on the show or let him heal up, “especially considering SummerSlam is already going to be a major draw with The Undertaker and Brock Lesnar.”

Oh but it wasn't serious
Why isn't he wrestling
It's just surgery

/sarcasm

I'd say let him heal up. With Lesnar/Undertaker on the card, Seth could defend against any babyface and won't affect ticket sales. Personally, I'd say go with Cesaro. Hell, have Cena endorse him as a "deserving" champion to try and take the belt from Seth.

^that, so much.
I'd say if people want Cena so bad at Summer Slam, have him be at Cesaro's Corner. Something like "As you know I won't be able to kick Rollin's ass, but I have a friend who wants to step up and take that challenge. *Cesaro theme plays, crowd goes wild, Hulk Hogan tweets some racist slur, everyone's happy* "

That just opens a spot for R-Truth to fill
