Liverpool youngster Sheyi Ojo is set to miss around a month of action with a fracture in his back, a club source has told ESPN FC.
Ojo, 19, had a scan after complaining of pain in his back following the team's preseason tour to the United States.
The promising winger missed the Reds' final two summer friendlies with Barcelona and Mainz as he underwent treatment on Merseyside.
Due to the nature of the injury, Liverpool are unwilling to put a concrete timescale on Ojo's return, but they believe he will likely remain sidelined until mid-September.
The Liverpool Echo reports that the injury was caused by a heavy workload rather than one particular incident and Ojo now requires a period of rest.
