Kevin Kilbane faces a spell on the sidelines after suffering a fractured cheekbone.
Wigan's Republic of Ireland international sustained the injury during Wigan's 5-0 hammering of Hull on Saturday.
"Killer has a depression on his cheek and you don't need to be a doctor to know it's fractured," said Latics boss Steve Bruce.
"He will have an operation and if all goes well he will be back in around six weeks."
