Ian Burchnall has confirmed Richard Brindley will be out for the next six weeks after the Notts County defender suffered a fractured arm.
The former Rotherham defender picked up the injury in Saturday's 2-1 win at Dagenham as the Magpies secured a vital three points and he will require an operation.
The centre-back had to be replaced at half-time of the clash against the Daggers having only just returned to action from an Achilles problem.
