Alabama leader Randy Owen's troubles with vertigo and migraines have continued, forcing the cancellation of two additional stops on the country trio's current tour. The group will not be playing their scheduled weekend (July 26-27) shows in Georgia and Tennessee.

According to Nash Country Daily, Alabama's July 26 concert in Columbus, Ga., and July 27 show in Bristol, Tenn., have been canceled. "Randy Owen has been advised by doctors that he can not perform this weekend as he continues treatment for vertigo and migraines," the band's management explains in a statement.

"We apologize for any inconvenience for those that have tickets to these shows," the statement adds, "but wish to reassure fans that Alabama is trying to reschedule these shows as soon as possible."

Owen's medical issues previously caused Alabama to cancel shows on July 19 and 20. The next concerts on their schedule are set for Aug. 16 and 17, thanks to a previously built-in break from the road.

Alabama began their 50th Anniversary Tour in January, and will stay on the road through late 2019. Fans can see their full concert calendar at TheAlabamaBand.com.
