Leeds United boss Simon Grayson: "Amdy did what we expected he could do and we're pleased.
"He's been training with us all this week and we sorted things out on Thursday morning. He's an experienced player who has played at the highest level and he is proven.
"He's a different type of player to the midfielders we have here and he is a good addition to the squad.
"He is short on fitness but that will come with time. He's here until January initially and we'll see how things go."
