Eoin Morgan has sustained a back injury and may miss England's second Twenty20 match against New Zealand on Tuesday.
The batsman jarred his back while diving to stop a boundary during the tourists' 40-run win over New Zealand yesterday.
The 26-year-old was England's top scorer during the win, hitting 46 from 26 balls.
Joe Root, who replaced Morgan in the field following the injury, would likely come into the side if he is unable to play on Tuesday.
