Defender Richard Naylor has returned to full training after slipping a disc in his neck last month. Midfielder Sylvain Legwinski is also on the road to recovery after injuring his ankle in training a week ago.
Neither will be ready in time to face Burnley on Saturday, but physio Matt Byard told the club site that both are moving in the right direction: "Richard is returning to full training and is making progress. We will continue to monitor him closely.
"Sylvain is also progressing well. He is doing some deep water running and should be doing some light jogging over the weekend. If all goes well, he is likely to return to training next week."
