Nigeria forward Victor Moses is unlikely to play again this year after hurting his thigh while playing for Stoke City in the Premier League.
Moses, who is on loan at the Britannia Stadium from Chelsea, is facing "at least six weeks on the sidelines" after picking up the injury in the 2-1 loss to Burnley on Saturday, according to the club's official website.
"He has a significant thigh injury which is likely to keep him out for several weeks," assistant manager Mark Bowen added.
Nigeria missed out on qualifying for the African Nations Cup that will be held in Equatorial Guinea in January and February.
