There has been a lot of speculation on The Undertaker's wrestling status for WrestleMania 33 as he reportedly underwent surgery recently. 

We recently shared some photos of Taker using crutches. PWInsider is reporting that The Undertaker was using those crutches to walk because he recently had hip surgery performed.  

There is no word yet on exactly when he had the surgery, but he apparently attended a wedding the first week of September and did not have the crutches at all.
