Wigan have injury worries over two key players ahead of Saturday's trip to Burnley.
Goalkeeper Chris Kirkland dislocated a finger during last weekend's 1-1 draw with Manchester City but played on for the full 90 minutes after attempting to put the digit back in place, while midfielder Paul Scharner has a hip problem.
"We'll be having all the scans and all the tests possible to find out the extent of the injury," said Wigan manager Roberto Martinez about Kirkland's injury.
"At the moment we feel it might only be a dislocated finger but we need to see exactly what the situation is and we'll find out more over the next 24 hours."
However, both Martinez and Scharner are more hopeful over the Austria international's problem.
"I picked up the injury the day before the game but it felt comfortable during the warm-up," said the 29-year-old Scharner.
"During the game it tightened up again and in the end I couldn't continue. We'll assess the injury, but hopefully I'll be okay for Saturday. I think I will be fine."
