Belmadi was signed on a season long loan deal from Marseille but because of injury Keegan has been unable to make judgement on the player with regards to offering him a permanent deal.
“I still have to talk to the board but at this moment in time he is likely to go back to Marseilles,” said Keegan.
“If one or two players leave then I would go back and ask because he has done very well and his training has been excellent but I just haven’t been able to get a proper look at him.
“We went to Newcastle with the reserve team last week but the pitch was so bad I offered the players a chance to pull out of the game.”
