His Injured Knee. And Yes He Will Be Coming Back Very Soon.
He isn't he is taking a break because he almost broke his neck in the match against Shawn michaels. undertaker will return at Summer Slam. As for Shawn he will return late 2009 or early 2010.
i think he will return because the undertaker said ''i will always return''.
Undertaker may return at summerslam not unforgiven
I think undertaker will return at royal rumble or at wreslemaina !
The Undertaker returned at SummerSlam of 2008.
Trple H is Recovering The Undertaker Is Too
they say that undertaker may return. its up to him though, so if he doesnt decide if he wants to return he wont. undertaker MAY NOT return because of how serious the injury was but there is never a correct answer. BUT MOST LIKELY YES.
