Barclays Premier League leaders Arsenal look set to be without winger Alexander Hleb (Achilles) for tomorrow night's trip to Newcastle.
Midfielder Cesc Fabregas (hamstring) missed the win at Aston Villa and remains a doubt, along with Abou Diaby (back).
Striker Robin van Persie continues to work on his match fitness following a knee problem.
Newcastle also have injury concerns and Sam Allardyce has resigned himself to losing defenders Abdoulaye Faye and Stephen Carr for the must-win clash.
Faye damaged a calf muscle on his return from a hamstring problem at Blackburn on Saturday. Carr, who replaced him at Ewood Park, felt a tightness in his own hamstring and also had to come off, and both are major doubts.
Steven Taylor (back) could return, but Claudio Cacapa, Michael Owen and Peter Ramage (all knee), Celestine Babayaro (back), and Damien Duff (foot) are still out.
