I was having a think earlier about how they could book the Summerslam main event between John Cena and CM Punk. First of all I think it's pointless if Cena goes over in the match, it will damage Punk and do nothing to get Cena over. It has been rumored that Cena is working banged up and may need some time off. It has also been rumored that a heel turn for Triple H is in the works, along with a feud with Punk. So with those things in mind, here is what I think should happen.
Throughout the match, Triple H should remain fair, until it looks like either man could win. If Cena goes for a pinfall, Triple H should fast count, if Punk goes for one, Triple H should slow count. Eventually this would lead to Cena confronting Triple H and declaring that he wants to do it "his way" (similar to MITB). But instead of Punk taking advantage from this, he'll simply sit back and allow Cena and Triple H to brawl, with Cena gaining the upper hand and throwing Trips from the ring. Triple H will then be taken by the medics from ringside with a kayfabe injury.
They will then resume the match as another referee comes down to officiate the match, where Punk will eventually get the win. The following Raw, Triple H will come out with a bandage or something to suggest a kayfabe injury and announce that he has "indefinitely suspended" John Cena. Punk should then come out and cut a promo declaring how Triple H inserted himself into that match with the intention to help Cena win, but then Cena refused to take any of his crap. Punk will then remark that despite him not being a fan of Cena, Cena was responsible for getting his suspension lifted and his title shot returned and the only fair thing to do is make sure Cena gets the same treatment. Triple H will argue that since Cena physically assaulted him, that he is liable for legal action and during this process he will remain inactive.
Eventually this will boil over and Punk and Triple H will go into full blown feud mode. Which will result in Cena returning after his time off a couple of months later.
