According to the Associated Press, George H.W. Bush was hospitalized on Wednesday after falling in his Maine home and breaking a bone in his neck, but a spokesperson for Bush says the former president “is fine.”

“His condition is stable,” wrote Jim McGrath on Twitter, “but he’ll be in a neck brace.”

At 91, Bush is the oldest living former president and has been hospitalized twice in recent years—for bronchitis in 2012 and for shortness of breath in 2014. A year ago this week, however, Bush celebrated his 90th birthday by going skydiving.

UPDATE 11:50 p.m.: A spokesperson for Maine Medical Center tells NBC News that Bush has sustained a fractured neck and will be kept overnight, but says it is “premature” to speculate beyond that.
