#1: Kane hasn't wrestled for WWE in 2020
While Glenn Jacobs has been quite busy with his political duties nowadays, his WWE character's onscreen appearances have diminished over the years.
Kane has made some appearances on WWE TV in 2020, with the most recent instance being during The Undertaker's final farewell at Survivor Series. Before that, he appeared earlier this year on an episode of SmackDown, where he had a brief reunion with Daniel Bryan during the latter's storyline involving "The Fiend" Bray Wyatt.
The Devil's Favorite Demon won and dropped the 24/7 title to R-Truth on an episode of RAW back in September 2019, and he hasn't been featured in a wrestling capacity since then.
The last in-ring match that Kane participated in was at Crown Jewel 2018, where he teamed up with The Undertaker to face Shawn Michaels and Triple H. Unlike his on-screen brother, Kane hasn't officially retired from WWE yet.
Kane is still featured under the SmackDown roster tab on WWE's official website.
An in-ring return from The Big Red Machine would certainly get a good pop when WWE fans start flocking to arenas in the near future.
