Jack Sowerby and Mickel Miller are currently being assessed after coming off injured in Saturday’s game at Lincoln City.
“They have both been assessed by Nacho but will be going for scans and that should give us more information, although a scan doesn’t always tell you everything and every individual is different," said manager Keith Curle.
“Alan Sheehan is progressing well and even though he hasn’t been playing in the last few weeks he’s been furthering his education on the coaching side of the game.
“If we only had two or three games left this season I’m sure Alan would be back in the side now but we are very mindful of the fact that we have a lot of games coming up and when Alan is back we want him to be involved in every single one.”
