Dusty Hill, bassist for ZZ Top, was injured at the Lone Star Events Center in Lubbock, TX, forcing the band to cancel their performance that evening. Hill has since undergone treatment for a fractured shoulder and the band’s dates on the current tour have been postponed through May 7.

“Dusty was suited up and ready to go when he tripped on a step while on his way to the stage for the start of Thursday’s show,” Carl Stubner, the band’s manager said. “It was very dark back there and the step – really a half-step – wasn’t lit so there’s no way he could’ve seen it.”

The shows in Shreveport, Biloxi, Lake Charles, LA, Chattanooga, Augusta, GA, Atlanta, Sarasota, Naples, Clearwater and Shawnee, OK will all be rescheduled.
