WWE.com is reporting that AJ Lee, Luke Harper and Dolph Ziggler all suffered injuries during WWE TLC. AJ was said to have suffered chemical conjunctivitis due to the hairspray used by Nikki Bella in their match, but the medical staff was able to flush her eyes with saline to help prevent any long-term vision damage.
As for Harper and Ziggler, they were both treated after their match with Harper getting five staples to the side of his head and Ziggler suffering a laceration on his head that was treated with skin glue and bandages.
Of course WWE.com loves reporting storyline and legit injuries with the exact same tone so it’s hard to be 100% sure, but I think it’s safe to say AJ didn’t actually get hairspray in her eyes.
