Rochdale's Simon Hackney is sidelined until March
Rochdale winger Simon Hackney is expected to be out for up to three months after undergoing surgery on an abdominal injury.
The 27-year-old summer signing from Colchester United is yet to make his Dale debut because of the injury.
His last game was back on 2 April for Oxford United during a loan spell, in a 3-0 defeat by Bury.
The former Carlisle man has made 173 Football League appearances, including a loan spell at Morecambe in 2010.
