Brooks & Dunn lead singer walks off stage during encore, leaving fans concerned for his health

Country music icon Ronnie Dunn has fans concerned after the country star abruptly walked offstage. 

During a concert in Indianapolis on Thursday, the 71-year-old Brooks & Dunn member was singing the band's iconic hit, "Boot Scootin' Boogie" during the show's encore when, at one point, he gestured that he was done. 

In a video posted to TikTok, Dunn finished his verse in the song before shaking his head at a member of his band, insinuating that he was no longer going to perform.
