One of the longtime members of the iconic Southern rock band the Allman Brothers is reportedly in “critical but stable” condition after suffering a fall. Guitarist Dickey Betts slipped while playing with the family’s dog in Florida, according to a post on Betts’ website.

“Betts, the ‘Ramblin’ Man’ singer-songwriter and founding Allman Brothers Band guitarist, went out to their backyard on Little Sarasota Bay and while playing with the family dog, slipped and cracked his head, causing bleeding from the brain,” the website reports. “Betts has been sedated at an undisclosed local hospital following the accident Monday evening at the Osprey home he shares with wife Donna.”

Betts, 74, is scheduled to have brain surgery Friday to relieve the swelling.

The website quotes Donna saying: “The family appreciates all of your thoughts and prayers during this very trying time. Dickey is a notorious fighter and he is displaying that now!”

The website adds: “Last month, Betts suffered a ‘mild stroke’ at his Sarasota home and had to cancel upcoming tour dates. A few weeks later, [Betts’ manager David Spero] announced Betts was responding ‘very well to treatment’ and on Sept. 14 posted to Betts’ social media pages that ‘Dickey Betts is raring to go. His recovery from his minor stroke is ahead of schedule and he has already started playing his guitar again.’”

Following the latest development, shows that had been scheduled for November have been canceled, the site reports.
