Former WWE star Mia Yim has hit back at a Twitter user for comparing Keith Lee and GUNTHER.During Lee's time with WWE, he quickly established himself as a top star by becoming a double champion in NXT. However, due to COVID-19-related health issues, he was forced to take time off from professional wrestling.Twitter user @GlobalFightRev recently praised the reigning WWE Intercontinental Champion for his work ethic while taking a dig at Lee. Reacting to the tweet, Yim claimed that her husband's health issues took a severe toll on him, and at one point, doctors even suggested that the AEW star would not live."Walter is awesome. “What keith Lee refused to do” When we weren’t sure if he was going to LIVE, the doctors told him if he elevated his heart rate, he could literally die. So working out, even jogging wasn’t an option. But go off about how he chooses to be fat and lazy," wrote Mia Yim.Check out Yim's tweet:The HBIC@MiaYimWalter is awesome. “What keith Lee refused to do” When we weren’t sure if he was going to LIVE, the doctors told him if he elevated his heart rate, he could literally die.
