The midfielder is thought to have ruptured his hamstring, an injury he has only just returned from.
He suffered the injury late on in the draw against Halifax, a match in which he came off the bench to score the equaliser.
The 22-year-old could need an operation. The club will find out later today.
The injury kept him out for three months earlier this season.
“It is a serious one,” manager James Rowe said.
"It is a real shame for the lad because he has done everything asked of him, he has done all of his rehab that we have asked of him.
"He is a top player so the temptation is always to start him but we have been patient.
"He scored the goal – such a high for him in front of his family – then 10 minutes later he had that big low."
Rowe added: "It is going to be a big ask of us to pick him back up but I am confident that he is mentally strong.
"He might need an operation.
"We will try to get him back at the back end of the season so it is a big loss for us to lose a player like that for the season.”
On whether they may look to find a replacement for him in the transfer market, Rowe said: “We may need to.
"We have got a few players coming back from long-term injuries so we need to see how they react.”
