Following Wrestlemania 29, The Undertaker appeared in two matches that involved The Shield. PWInsider.com is reporting that Taker is in much better health these days, and that WWE is keeping the door open for him to return whenever he wants. When he returns, it will most likely be involved with The Shield.
His last match was with Dean Ambrose last week on Smackdown. He is expected to stay off television for the time being. He is not scheduled to be at WWE Extreme Rules and was only considered for a match in emergency situations. These would have been if top superstars would have been out, including John Cena.
Undertaker changed his diet and workout routine prior to Wrestlemania 29. He has also been booked in matches to help his body, including what they are calling "smart matches" against CM Punk and Ambrose.
