Bryan Alvarez is reporting in today's F4WOnline.com update that "there is no guarantee" that The Undertaker's broken orbital bone will be healed in time for Summerslam, which was the original belief. We'll know for sure after next week's TV tapings since that's when the road to Summerslam will kick off. Taker's career has been on borrowed time for years, as he's in need of a hip replacement and has been described as being in rough shape for the last decade-plus. He's made a ton of money and invested well, so there's no real reason for him to keep going. He's best off working as limited a schedule as possible and retiring at Wrestlemania.
