I'm told Vince McMahon has been "flipping out" over the injury to Alberto Del Rio. While it's not Del Rio's fault he got a concussion, Vince is in panic mode trying to find a replacement for the World Heavyweight Championship match at No Way Out. McMahon has been pushing the writing team to come up with a suitable replacement for a back-up plan.
While a replacement for Del Rio has yet to be named, or even confirmed given the fact he's expected to be reevaluated today, there are three names currently being talked about. The three names are Dolph Ziggler, Kane and Ryback. Kane replaced Del Rio in recent live event matches and while creative would be forced to forget about his involvement in CM Punk/Daniel Bryan and drop him from the triple-threat match for the WWE Championship, he does provide them with a reliable option.
Ziggler, who has been pushing for a big singles run, seems to be a likely candidate but some doubt Vince will go with it and make a decision to rush Ryback into the role. This of course would carry a huge risk as there are plans to ease Ryback into Smackdown's main event scene.
