Poison are in the midst of their '80s rock-centric Stadium Tour with Def Leppard, Mötley Crüe, and Joan Jett, but they were forced to cancel their Nashville set on Thursday night (7/30) when frontman Bret Michaels had a medical emergency. In a statement on Twitter, Michaels wrote, "To the incredible fans in Nashville, thank you for all your well wishes!! I was truly fired up to get on stage in the Music City and perform, but due to an unforeseen medical complication & following hospitalization, it was not possible. I send my deepest apologies for being unable to rock the stage tonight!!! I'm working on being back 100% very soon & hope you rocked hard with my friends Motley/Leppard/ Joan and Classless Act!!!"
Sources tell TMZ that Michaels "may have had a bad reaction to medication that is related to COVID ... medication that triggered a reaction as a result of his diabetes."
