John Terry broke a bone in his foot during Aston Villa's defeat to Sheffield Wednesday on Saturday, the defender confirmed.
Terry, 36, limped out of the game midway through the first half and was taken to hospital, where he learned he broke his fifth metatarsal.
Terry posted a photo of his foot in a boot on Instagram, writing: "Devastated is an understatement to how I'm feeling tonight.
"I have just had the news that I have broken my fifth metatarsal. I will be doing everything I can to get back fit as soon as possible."
Villa boss Steve Bruce could not hide his disappointment following Aston Villa's surprise 2-1 home defeat.
