When the accident happened, the 74-year-old musician was recovering from a mild stroke that happened last month and was said to be recovering well. He was doing well enough that a series of dates that had been canceled were rescheduled.

On Instagram, Dickey's longtime friend and manager David Spero asks everyone to keep Dickey in your thoughts and prayers as well. "It was just a few days ago that Dickey told me how excited he was to get back in front of his fans in November," he writes.

Those November dates, including a Nov. 1 show at Bell Auditorium in Augusta, have all been canceled.
