Wigan Athletic No2 Eric Black says there's no excuse for Amr Zaki returning late from international duty with Egypt.
"Most of the players were told to report back and certainly he was meant to be back on Monday," Black told Sky Sports News.
"He [Zaki] was meant to be back on Monday, obviously that hasn't materialised and we will just have to wait and see when he does return.
"We had initial contact about the hamstring injury after the game and obviously we have spoken to Mido, who arrived back on Monday, so we are led to believe he has a hamstring injury and he is being treated for that, but that's as much as we know at the moment."
