Former Fleetwood Mac guitarist Lindsey Buckingham has suffered vocal cord damage after undergoing emergency open heart surgery last week.

Buckinghams wife, Kristen, said that while the rock legend and his heart are doing well, it remains unclear whether or not the damage to his vocal cords is permanent, though she is hopeful it is not.

Needless to say, all touring and shows currently scheduled have been put on pause for the moment as he gathers the strength to heal completely, she wrote in an Instagram post Friday.
