Warrington suffered a back injury in the win against Dagenham and has been undergoing treatment.
If he doesn't make it then one of Steve Cann or Mark Oxley will deputise - both lads played one half each in last night's reserve fixture at home to Hull.
The Millers lost out 2-1 with goals from Michael Bridges and a Nathan Doyle penalty coming either side of Jamie Yates' headed equaliser. Liam King was also red carded.
Meanwhile, fans still wait for news from the administrator of a takeover as the rumour mill continues to churn.
