Captain has slight tear to knee ligament
James Wesolowski has sustained a slight tear to his medial knee ligament.And depending on the effect an injection has will determine whether Latics' captain plays again this season.
Manager Lee Johnson said: "We will have to see how he comes through the injection - he could dramatically improve or it could make no difference.
"James won't be ready for Tuesday, but possibly could be for Saturday or he could be out for the season. We will have to see how it settles."
Wesolowski sustained the injury with virtually the last kick of the npower League One match at Preston North End.
