To follow-up on the rumor that The Undertaker is returning on next week's episode of Monday Night Raw in Kansas City, Missouri, I'm told WWE has booked travel arrangements for him. While I'm not 100 percent certain on the details, it looks like he could be in St. Louis for WWE Battleground on Sunday. A hotel for him has been booked and his departure date is July 21, 2015 (the day after Raw).
This certainly gives credence to earlier reports that indicate Undertaker will return on next week's episode of Raw to build to a match at SummerSlam on August 23, 2015.
The takeaway is Undertaker could appear at Battleground, which would still mean a return to WWE next week.
