Undertaker training again but may not return for WrestleMania 31

We're now two months removed from WrestleMania 30 this past April 6, 2014, at the Mercedes-Benz Superdome in New Orleans, Louisiana, where Undertaker's streak ended at 21 after a third F-5 from Brock Lesnar and the most shocking three count from a referee in pro wrestling history.

Ad nary a peep from "The Phenom" since.

The conventional thought has long been that when the streak ended, so would 'Taker's career. After all, he's good for one match a year at this point and each year it has become increasingly less likely that he will continue wrestling beyond his latest match.

And considering (most) wrestlers, per tradition, go out on a loss, it's not unreasonable to think the Lesnar match was the last one.

According to the Wrestling Observer, Undertaker is back training in the gym but when asked in recent weeks if he will be back for WrestleMania 31 next year in Santa Clara, California, he's said "it's not looking good". In fairness, similar reports have surfaced in years past and the Observer is sure to mention that as well. It always looks like it won't happen, then we get closer and closer to WrestleMania, and suddenly the gong hits.

Part of the reason for that is a personal responsibility Undertaker feels in regards to his place in the industry. He also admitted in an interview last year that he would feel like he was letting Vince McMahon down if he didn't perform at WrestleMania.

But that was last year, before the streak was broken, before he piled on a few more injures to an already ailing body, and before he turned 49-years-old. He'll be 50 by the time next year's "Showcase of the Immortals" rolls around.

We'll have to wait and see if he gets the itch and can't avoid scratching it for one more year. The question I leave you with is this: Should he just retire and ride off into the sunset? Or do you want him back for (at least) one more match?
