A WWE source told sports blog Corey Unfiltered (coryradford.blog.com) Friday that Alberto Del Rio suffered a "serious concussion" at last Tuesday's SmackDown taping in Columbia, South Carolina. During a skirmish, Sheamus slammed Del Rio's head against the metal WWE logo, leading to his concussion. Kane replaced Del Rio as Sheamus' Steel Cage Match opponent in the post-taping bout and at Saturday's SmackDown live event in Salisbury, Maryland.
Del Rio's injury puts his World Heavyweight Championship Match against Sheamus at No Way Out on June 17 in jeopardy since WWE officials believe he will not receive medical clearance in time for the pay-per-view event. Contingency plans are being discussed in case Del Rio is unable to compete, including removing Kane from the WWE Championship Match against CM Punk and Daniel Bryan. Other plans broached include a Battle Royal or a Beat the Clock Challenge to take place at this Tuesday's SmackDown taping in Manchester, New Hampshire
Meanwhile, WWE heads Vince McMahon and Triple H are becoming increasingly worried that Del Rio cannot be relied on due to injury concerns. He is being compared to former WWE star Mr. Kennedy (now known as Mr. Anderson in TNA Wrestling), whose reputation for being injury prone partially led to his release from the organization in 2009.
