Midfielder Joe Riley had to leave the pitch just before half time on Saturday afternoon after a collision in the middle of the park had seen him tumble to the floor heavily.
Having tried to shake off what appeared to be a knock to the shoulder, he eventually signalled that he couldn’t carry on.
To add to the frustration the game was his first in just over a fortnight, with a foot injury ruling him out of the league games against Barrow, Exeter and Harrogate.
“We had a few people moaning about how it had happened,” boss Keith Millen said. “I don’t know if it was a foul or an accident.
“Someone’s possibly run onto the pitch and collided with him, and it’s around his shoulder area, I don’t know yet how bad. I’m not sure if it popped out, we’ll have to wait and see, but he didn’t look good.
“He fell and when he said he could carry on, which is testament to him and the type of person he is, I thought he was ok, but obviously that’s not the case. I don’t know the details of that yet.”
And on Brennan Dickenson, who was absent from the match day squad, he commented: “He’s not too bad actually. We should see an improvement in him over the next few days.
“It looks like it was more a kick than a strain, so it should settle in the next couple of days. He got s whack in the last game and we weren’t sure if it was just a contact injury or a strain of a muscle.
“It looks more like contact, so hopefully he might be available for Tuesday.”
