John Cena commented on his elbow injury that was very visible on last night’s episode of Raw, writing on Twitter, “To all those wondering how a baseball got stuck in my left elbow. It’s…complicated. Ill be fine for #summerslam @WWEUniverse @WWE”As mentioned earlier, WWE played up to the injury on their website, questioning if John Cena would be at 100% for his match against Daniel Bryan at the SummerSlam pay-per-view.“He can and has fought back through worse. As for whether he’s truly at 100% when he puts his title on the line? That, at least, is no longer a given.
