He had hoped to return after missing out on the QPR and Stoke games, but Peter Grant says:
"Calum is still struggling and we have to be careful of his welfare because he is Tottenham's player.
"We will give him as much chance as we can and obviously he is desperate to play in the game.
"We will give him until Saturday morning but we won't take chances with him because he is too important to us.
"We would rather he missed one game than three or four."
Chris Powell is still doubtful as well and Peter adds:
"Chris is improving but the Gillingham game coming along too quickly is a possibility."
Teddy Sheringham has a thigh problem and Peter adds:
"Teddy knows his body better than anyone and you have to be careful, especially with a thigh injury, because it is a big muscle.
"If it is not right and you get a bad injury it could be up to six or eight weeks."
There are still plenty of options for Alan Pardew, however, and Peter concludes:
"We look a better side when everyone is available because there were a few changes against QPR and we ended up with a poor performance.
"Now there is a competitive edge and that makes us a better team."
