Harnell made the announcement with the following Facebook post, "I'm sorry to inform everyone that I'm no longer the lead singer for Skid Row. I thank the fans for their love and support!"

The band issued the following on Wednesday, "To the Skid Row faithful, As you may know, Tony Harnell quit the band yesterday. We found out about his decision the same way all of you did, via his post on social media. He had posted that he was no longer in the band before informing the band personally.

"The last we spoke with Tony was on December 17th. He was in the hospital being treated for 'bronchitis with asthmatic symptoms'. We were all very concerned and offered any assistance we could to help him get healthy. Due to his condition we were forced to cancel our show in Chicago on December 19th. The next time we heard anything was his post yesterday.
