Buttler stepped into the role for the fourth Test in Southampton, with regular wicketkeeper Bairstow struggling with a broken finger, but the Yorkshireman will be back behind the stumps at the Oval.
A statement on the England and Wales Cricket Board’s website read: “Jonny Bairstow will keep wicket after recovering from a broken middle finger.”
Captain Joe Root, who named an unchanged team for England’s final Test match of the summer, told a press conference at the Oval: “I hope (Jonny) uses it as a real driving force to keep improving.”
Root also spoke about the moment England’s all-time record run-scorer Alastair Cook informed him this Test would be the last of his career.
Asked for his reaction when Cook broke the news, he paused before saying: “Sad. It’s been an outstanding career - 12 years at the top of the order. To have a record like that is some feat, especially in these [English] conditions for the majority of it.”
