Wigan boss Roberto Martinez has confirmed Charles N'Zogbia may be ruled out of the crunch relegation six-pointer with Burnley.
The Frenchman was forced off during the second half of Wigan's defeat against Aston Villa on Tuesday night and Martinez admits he is concerned N'Zogbia will miss the tie against Burnley this weekend.
He said: "The injury to Charles was a big negative for us, and we will assess him in the next 24 hours to see if he is okay for Saturday.
"Charles very rarely has to come off in a game and, as a result, it is a very big concern for us."
