There is mounting evidence that The Undertaker has possibly retired from the WWE, according to a report at inquisitr.com. One big change that has been observed is his wife Michelle McCool is no longer 'kayfabing' their marriage. Pre-WrestleMania 30 she wouldn't post photos of her husband on social media, and she would only reference "hubs". She has now started posting several photos on instagram that show her and Undertaker, some that even mention his name. There's an implication that Undertaker has now moved on from WWE and is no longer required to maintain his act in public forums. Another indication of Undertaker's possible retirement comes from his recent appearance at Texas Comic Con. He reportedly told some fans that he didn't even plan on attending WrestleMania 31. However, it does seem a bit of a stretch that he'd just casually give those comments away. He's still a private man and holds an old school wrestling mentality. Commenting on wrestling related issues would be seriously out of character. But then, appearing all over social media enjoying his family life is seriously out of character. He looks like he has moved on, he looks like he is enjoying his post-WWE life. Whether he has officially retired from WWE can't be confirmed, but Michelle McCool is certainly casting Undertaker in a way that suggests a change. If this is the end, it will be bittersweet. He did the right thing by sacrificing his 21 year WrestleMania winning streak, but the actual match with Brock Lesnar at WrestleMania 30 was a major disappointment.
