The veteran rocker began the North American leg of his The Hits tour in Atlanta, Georgia on Wednesday (15Jul15) and he began suffering a throat condition shortly afterwards.

Doctors ordered him to cancel his performance in Tuscaloosa, Alabama on Thursday (16Jul15) so he could rest his vocal cords and avoid axing further shows.

In a statement on the Tuscaloosa Amphitheater's page, Stewart says, "It breaks my heart to cancel knowing that so many people have made plans but I don't want to give my Tuscaloosa fans a performance that isn't my best."

Stewart is hoping to be back on stage in Toledo, Ohio on Saturday (18Jul15).
