WWE WrestleMania 32: 8 Potential Run-Ins For Undertaker Vs. Shane McMahon

7. Shawn Michaels

Michaels has obviously retired from wrestling, but was apparently offered a substantial amount of money to appear in the 2016 Royal Rumble match. A 'Mania run-in only carries a very minimal risk of injury, if done right - and I'm willing to bet that he's still more than capable of throwing a mean superkick. HBK and Undertaker have feuded for large stretches of their careers, and there'd be no prizes for guessing which side Shawn would take were he inclined to interfere...unless the many epic battles between the Heartbreak Kid and the Deadman have instead forged a deep respect.
