Ritchie Jones is a doubt ahead of this weekend's League One visit to Millwall.

The young midfielder missed Tuesday evening's Johnstone's Paint Trophy clash with Leicester with a groin problem and is rated 50-50 to feature at The New Den.

Willie Boland remains sidelined with a knee ligament injury, while Ben Clark is still a little way from rejoining full training following a bad ankle sprain.

 Millwall welcome back injured trio Gary Alexander, Neil Harris and Lewis Grabban in time for Saturday's game.

However, midfielder Marc Laird is still ruled out with a hamstring problem and Danny Spiller has aggravated a groin problem and will miss out.
