Spackman said: "Darren is having another scan and X-ray and we should have the results of those by Thursday morning, naturally we're hoping that the injury is not too serious.
"One or two other players have been in for treatment on Wednesday and again I should have a clearer picture on Thursday morning who is likely to be available for Saturday."
