3 Doors Down says on its website that founding member and guitarist Matt Roberts has left the rock band because of health problems.
The statement Wednesday says Roberts has problems with blood circulation and other health issues. It calls the split amicable.
Roberts grew up with bassist Todd Harrell and lead singer Brad Arnold in Mississippi. Together they formed the band in Escatawpa, Miss., in 1996.
Arnold says Roberts will be welcomed back if he's able to return.
Guitarist Chris Henderson and drummer Greg Upchuch will continue to tour.
