PA Sport is reporting that Ryan Green is a doubt for tomorrow with a shoulder problem.
The Welshman was subbed after an hour against Chesterfield with the injury and will be checked before the starting lineup in named. The site also reports that Ryan Valentine is back in training but is unlikely to feature after missing the last five months with a hip problem.
For Rotherham they will be missing central defender Johnny Mullins after an operation, while veteran keeper Andy Warrington is still struggling with a foot injury. Rookie Jamie Annerson is expected to continue in goal, with the 22 year old having played only one senior game before joining the Millers last summer.
Meanwhile, former Bulls loanee Josh Gowling is set to leave Gillingham in the summer. His agent has told Sky Sports that the former Bournemouth man has not been offered a new deal, despite being told one would be coming, and they were now looking elsewhere for next season:
"It is a shame it has come to this as Josh loves playing for Gillingham and he loves the fans, but he has no choice to move on after what has happened. I am talking to interested clubs in Josh with clubs higher up the league keen on signing him."
