The 32-year-old scored only his second goal for City in last night's victory over Mansfield, but had to go off 20 minutes from time after picking up a knock.
He said: "It's the same ankle that caused all the problems earlier in the season and I'm just hoping it's a strain this time rather than anything serious and that I will be okay in a couple of days. I've only just got back in the side and I don't want to miss any games now, especially Scunthorpe.
"It's a big match for us and after gaining revenge against Mansfield for an earlier defeat in the league this season, we'd love to do the same against Scunthorpe. It was a tremendous performance by the entire team against Mansfield last night. It was great to get on the score sheet again and I think the early goal made all the difference to us."
Gary Bradshaw opened his City account in a rare start, but also picked up a knock and was substituted early in the second half.
The 19-year-old said: "I'd always dreamed of scoring at Boothferry Park and it was great to see the goal go in. It meant a lot to me.
"I'm not so sure what happened regarding the injury. I can remember trying to stretch for a pass and I felt something pull in my back. I tried to carry on after half-time but it wasn't any good."
Richard Sneekes also went off with flu troubling him.
Caretaker manager Billy Russell said: "We had to take Richard off because he wasn't feeling very well. To be honest, he wasn't well before the game but he wanted to play and I thought he was outstanding. He controlled the game."
