CM Punk underwent knee surgery last week and is expected to miss some time. Punk is still being advertised to appear on RAW. His injury is expected to be included in storylines as it was addressed in a statement made by Vince McMahon and released on WWE.com.
Punk's injury sets up perfectly for the WWE Champion to be wheelchair-bound. This was the case for Bret Hart in 1997 during the Canadian legend's hot heel run. Should Punk spend the next several weeks being wheeled around by Paul Heyman, he will join an exclusive club.
Many WWE superstars have included wheelchairs in their gimmick arsenal for both legitimate and kayfabe reasons.
More times than not, wheelchairs do anything but protect WWE stars. Many times, they are a source of even more danger.
