The Wrestling Observer reports that The Undertaker, 45, suffered a broken orbital bone and nose in his 5/25 match against Rey Mysterio on 5/25 in Cleveland. In addition, Undertaker also suffered a concussion.

It is believed the injury occurred from taking the seated senton move by Mysterio during the match that aired this past week on Smackdown. At this point, it is considered 50/50 if Undertaker can compete at the 6/20 Fatal Four way match.

Due to the Undertaker’s absence, Mysterio, who is scheduled for a vacation, has been called back to action. If Taker can not compete at the PPV, it is likely that Mysterio would take Undertaker’s spot. Changes could be taking place as soon as the Smackdown tapings tomorrow.
