#2. Sami Zayn tears his rotator cuff whilst making his way down the WWE ramp
Whilst there have been some shocking injuries in the ring over the years, current Intercontinental Champion Sami Zayn didn't even make it to the ring before he suffered one of the worst injuries of his career. Back in May 2015, Sami Zayn came out to challenge John Cena on an episode of WWE RAW and may have been a little too excited to be in front of his hometown.

Zayn threw his arms up in order to hype up the crowd, but as he did so he managed to tear his rotator cuff before he had even stepped through the WWE ropes.
Zayn's arms went limp and it's obvious that Cena was forced to call an audible since the match was much shorter than expected and it allowed Zayn to head back for treatment.
The injury sidelined Zayn for the rest of 2015 and seems to be a recurring injury for the WWE star since he was recently sidelined for more than a year when he tore both of his rotator cuffs once again whilst wrestling in Montreal.
