After weeks of speculation and doubts due to John Cena's broken nose, the big title match is now official for SummerSlam: Seth Rollins will defend the WWE World Heavyweight Championship against John Cena, who will put the United States Championship one the line in a Winner Takes All match. Cena hasn't been on Raw since July 27 when he legitimately suffered a broken nose when Rollins nailed him with a high knee that was a little too aggressive. Cena underwent surgery the next day to repair the break and his status for SummerSlam was questionable with Triple H saying it was "50/50" in terms of Cena actually wrestling. Since then, Rollins has mocked Cena while also challenging to a Title vs. Title match at SummerSlam. When Cena appeared on Tuesday's live Tough Enough broadcast, he looked fine and basically said that he would be ready for SummerSlam, although he didn't officially accept the challenge. The match was confirmed by WWE.com hours later, so WWE was likely happy enough with Cena's health to announce the match. This will be the second biggest match at SummerSlam after Undertaker/Lesnar and it will be interesting to see how WWE books it. If John Cena wins then he's a 16 time World Champion, which would tie him with Ric Flair's recognized record. If Rollins wins, would it be cheap or a clean loss for Cena, who rarely loses clean? A disqualification or count out finish is possible to set up another match down the road because they are expected to keep feuding after SummerSlam. WWE will need a strong main event for Night of Champions in September and a Champion vs. Champion match could be the headliner since Lesnar and Undertaker are unlikely to work that show.What do you think will happen in their match?
