In a tweet from his official account, Bonaduce wrote, “Some news to share. I’m taking temporary medical leave from my radio show. I will share more when I know more. I am still working to receive a diagnosis. What I do know is that I need time to focus on my health. I love my job and talking to you guys and I’ll be back on the air soon.

Bonaduce included a photo of himself with a cane in his tweet.

He added: “Charlie Chaplin. Willy Wonka. Dany Bonaduce. I joined the club of cool guys with canes.

According to KZOK, Sarah will continue to host the show in Bonaduce’s absence.

Celia Bonaduce said Bonaduce’s illness is truly a mystery, adding that her balance “super sucks” and doctors in Seattle are still working to figure out why.
