Durham all-rounder Adam Hickey will have surgery to repair the fracture of his right collarbone suffered trying to take a catch in Sunday's T20 Blast defeat by Lancashire Lightning.
The 20-year-old had to leave the field during the Lancashire innings and was sent to hospital for an X-ray.
Hickey made his first-class debut for Durham last season and has played four T20 games in 2017.
He has also played for England at under-19 level.
No timescale has been given by the club as to his absence and recovery.
