A personal crisis suffered by singer Johnny Van Zant has wiped Lynyrd Skynyrd's next two tour dates off the schedule.

The band had been scheduled to perform at the Golden Nugget in Las Vegas tonight (Dec. 2) and tomorrow, but a recently posted update to the band's social media platforms informed ticket holders that both shows have been canceled. "Johnny Van Zant has a family emergency of the greatest degree," reads the announcement. "Lynyrd Skynyrd looks forward to returning to The Golden Nugget in 2017. Please contact The Golden Nugget box office for refunds."

Van Zant sparked fans' concern earlier this year when he was taken to the hospital with what appeared to be pneumonia; fortunately, doctors discovered he'd only contracted bronchitis, and he was able to return to the road after a little rest and recovery. It sounds like Van Zant's current concerns are quite a bit more serious, but here's hoping whatever emergency he's dealing with now gets cleared up quickly.

In other Skynyrd news, the band will be the focus of an upcoming documentary to be aired on the CMT network in 2017. Titled If I Leave Here Tomorrow: A Film About Lynyrd Skynyrd, the film is set to be helmed by Stones in Exile director Stephen Kijak, and purports to take "an innovative and cinematic approach to explore the music and rich backstory of the legendary American band."

Guitarist Gary Rossington has promised to tell the "no-holds-barred story" of the group — and Van Zant, whose brother Ronnie co-founded Lynyrd Skynyrd, echoed with a pledge to offer a unique family perspective on their legacy.

"Gary will finally get a chance to tell his side of the story, being there since the beginning," he added. "Ronnie was a father figure to him, as much as a friend. I’m so happy that this is happening for him and the band. I’m also glad to share stories with my brother Donnie, growing up in the Van Zant family."
