Nathan Followill was treated for broken ribs after an incident while on board the band's tour bus last Saturday night.

Kings of Leon have been forced to postpone a concert in Saratoga Springs, New York after the tour bus he was on stopped suddenly to avoid a pedestrian who had wandered in front of it.

The band's official Facebook page elaborates further, saying: "Due to an accident on their tour bus, Kings of Leon will unfortunately have to postpone tonight's show in Saratoga Springs, NY. The band [were] en route to their hotel after their show in Boston when a pedestrian jumped in front of their tour bus, causing the bus to stop short, injuring Nathan Followill.

"Nathan is being treated for broken ribs, but is doing well. The band will postpone the show that was planned for tonight August 10th, until further notice. Refunds for ticket holders will be available at point of purchase."

Broken ribs, as anyone who has suffered from them will attest, are a notoriously painful injury, restricting your movement for weeks. Simply put, it's not a good injury for a drummer to receive. 

Kings of Leon currently have two months left of their 'Mechanical Bull' tour, with it scheduled to conclude in Mexico City on October 12th, and there is no word on whether (or how much) this injury will impact the band's schedule.
