Reid turned his ankle during the weekend defeat at Crewe and although he lasted the full 90 minutes the Iron skipper may miss out.
Manager Brian Laws will assess Reid’s fitness before deciding whether to recall fellow centre-half David Mirfin alongside Niall Canavan.
Mirfin has only recently returned from a two-month lay-off due to a knee injury.
Laws, who has no other new injury or suspension worries, is expected to retain Akpo Sodje and Karl Hawley up front.
Sodje is searching for his first goal since joining the Iron in early January, three games ago.
Midfielder Josh Walker returned to the substitutes’ bench on Saturday following an eight-game absence due to an ankle injury and illness and is pushing for his first appearance since late November.
