It was reportedly in this week’s Wrestling Observer Newsletter that Sasha Banks is currently dealing with what has been described as an “undisclosed injury.”
Banks has responded to this report on her Tumblr account. She responded to a fan by saying “Not these reports again.” and then “You’re expected to wrestle every single show, if not you’re injured.”
Banks has not wrestled since the December 28th episode of RAW against Becky Lynch. She has appeared on WWE TV since then but has not worked a match. I'm not saying that this is the case with Sasha Banks, but there have been instances when wrestlers were injured but they would go on social media to deny reports. WWE has been quiet on some injuries and they will selectively choose which injuries get mentioned on WWE.com.
