The striker left the action against West Bromwich Albion in the 72nd holding his back after just failing to score from a sitting position during a goalmouth melee.
And although it’s too early to say, there’s a possibility that the injury could keep him out of the African Nations Cup Tournament which kicks off in Equatorial Guinea on January 17.

Whether the fresh injury will keep him at home is in the balance but the potential for a club v country battle is very much on the cards.

“We’ll know a lot more over the next few days/weeks.”
