Nigeria defender Ryan Alebiosu is set for a lengthy spell on the sidelines with injury, DAILY POST reports.
Alebiosu sustained the injury during Blackburn Rovers' Sky Bet Championship clash with Stoke City last Tuesday.
The right-back left the pitch four minutes before the break.
It has now been confirmed that the defender needs an operation.
Blackburn Rovers boss Tony Mowbray said Alebiosu will be out of action for three to four months.
The 24-year-old has struggled with fitness problems this season.
