Rossington, who underwent open heart surgery in February, was advised by his doctor to rest in order to combat medical fatigue. His doctors determined that he had suffered a mild seizure recently and has since been ordered to at least three weeks of house rest prior to returning to the road.

This interrupts the band’s current co-headlining tour with Sammy Hagar. Lynyrd Skynyrd originally nixed five concerts on the Party Of A Lifetime tour and are now pulling out of all remaining shows. The group anticipates making up those missed shows at a later date.

“We’re hopeful that Gary will have a speedy recovery and look forward to performing in the near future,” Skynyrd lead singer Johnny Van Zant said.

Meanwhile, Lynyrd Skynyrd are already looking forward to getting back on the road. The band has its own Vicious Cycle tour plans worked out – they’re back on stages from August 23 through the start of October.
