John Driskell Hopkins, one of the founding members of Zac Brown Band, has revealed he's been diagnosed with amyotrophic lateral sclerosis (ALS).
The 51-year-old musician announced his diagnosis in a video shared to the Zac Brown Band's social media accounts on Friday.
The video also appeared to serve as a launch for Hopkin's ALS research foundation, Hop On A Cure, with the clip telling fans who want to help to "Text 'HOP' to 345-345 to make a donation."
The Hop On A Cure website noted that Hopkins was diagnosed with ALS in December 2021.
Hop On A Cure "is committed to supporting research to prevent, reverse, and cure ALS while raising awareness, building a compassionate community, and unleashing the healing power of hope.
Hopkins has been a member of Zac Brown Band since 2005. Along with being the bassist and a vocalist for the band, Hopkins also plays the guitar, ukulele and banjo.
