Luke Bryan has postponed the second show of his 2014 tour -- originally scheduled for Friday (Jan. 17) in Lexington, Ky. -- following a stage collapse about an hour after his Thursday night concert in Columbus, Ohio.

Bryan's set was being deconstructed after a concert at the Schottenstein Center when a forklift reportedly struck the stage, according to WCMH-TV, the NBC affiliate in Columbus.

Four workers sustained injuries, though none were life-threatening, the station reported. Officers from Ohio State University police department were called to the scene just after midnight. The city's fire personnel also responded to the incident and treated workers on site.

Bryan's publicist confirmed that Friday's show has been postponed.

"Tonight's Luke Bryan concert in Lexington, Ky., will be rescheduled for Feb. 21 due to damage sustained to a piece of the stage during production load out after last night's show in Columbus, Ohio," according to a written statement. "The damage occurred after the show had ended, and no fans were in the building. The tour's team will make the necessary repairs to the production elements so the tour may continue."

According to Bryan's website, he is scheduled to appear Saturday in Knoxville, Tenn., before heading north for shows on Jan. 23-24 at Mohegan Sun Arena in Uncasville, Conn., and Jan. 25 at Madison Square Garden in New York City.
