Jason Roy has been ruled out of England's three-match T20I series against Pakistan after sustaining a left side strain.

Roy picked up the injury this week during the white-ball squad's preparations at Emirates Old Trafford, and had a scan on Wednesday.

He will remain with the England set-up and will undergo rehabilitation work ahead of the Australia white-ball series, which starts next month at The Ageas Bowl.

Roy struggled for form during the ODIs against Ireland, making 25 runs in three innings, and his absence may offer an opportunity for Tom Banton to open the batting alongside Jonny Bairstow, just as he had done in Roy's absence in New Zealand before Christmas, where he played the first of his three T20Is.

England play the first of their three matches against Pakistan on Thursday, with the subsequent two games coming on Sunday and Tuesday, all at Old Trafford.
