#4 WWE RAW Superstar Naomi
From the 01:06 mark of the video below, you can see that Naomi tried to pin Aksana after a sunset flip during their one-on-one match on WWE RAW in February 2014.
Aksana countered the pinfall attempt with a somewhat reckless right knee into the left eye of Naomi, who immediately gritted her teeth and held her eye.
The former Funkadactyl won the match with a split-legged moonsault but it was obvious to the WWE Universe that she had suffered a serious injury.
The injury was so severe that, according to a statement on WWE’s official website, Naomi was unable to travel on an airplane due to the pressure differences between her sinus cavity and the back of her eye socket.
After a six-week absence from WWE television, Naomi returned to action in March 2014 by teaming with Cameron to defeat AJ Lee and Tamina on RAW.
Unfortunately for Naomi, the injury came at a time when she looked set to receive a major push as a singles competitor, including a rivalry over the Divas Championship with AJ Lee.
Those plans were axed and Lee ended up dropping the title to Paige one night after WrestleMania 30.
