Fleetwood Mac singer Lindsey Buckingham has been forced to postpone his U.K. tour after his guitarist sustained a serious back injury.

The rocker was due to kick off the seven-night trek at the Symphony Hall in Birmingham, England on Thursday but he's pulled all his gigs so his bandmate can recover.

A representative for the star tells NME.com, "Lindsey Buckingham unfortunately needs to postpone his upcoming UK shows as his guitarist has severely injured his back and is not able to presently perform. All tickets will be honored at the soon-to-be announced rescheduled dates."
