Manager Brian Barry-Murphy provided an injury update on Captain Eoghan O'Connell in his post-match interview on Saturday.
O'Connell was forced off in the first half against Crewe Alexandra through injury and BBM has confirmed that the Dale skipper is likely to be out for some time.
"Eoghan has damaged his hamstring," said the Boss.
"There’s no timescale - but it looked a pretty serious hamstring injury and by the nature of the way it happened, Sam Kelly, the Physio, thinks it could be a significant spell on the sidelines."
