Joseph Job will be keen to continue up front with JFH after his brace against Norwich, should Viduka fail his test. If Colin Cooper is fit he will once again step into the breach, if Riggott fails his test. It will be Coops 600th career game in the league if he plays.
Apart from the long term casualties Boro have no other new injury worries, so it is quite possible that boss Steve McClaren will start with the same team that beat Norwich.
Personally I would love to see James Morrison given the nod against Szilard Nemeth. With Morrison and Stewart Downing down the wings it will be a stern test for United's sometimes dodgy defence.
Possible Boro starting line-up (my preference):
Schwarzer, Reiziger, Queudrue, Southgate, Cooper, Morrison, Parlour, Zenden, Downing, Job, Hasselbaink
United will be without Wayne Rooney who was suspended yesterday following his spat with Bolton's Tal Ben Haim, so Alan Smith will be their only recognised forward.
John O'Shea has also been ruled out with a thigh injury but Gary Neville and Eric Djemba-Djemba should return after flu.
United from:
Carroll, Howard, G Neville, Heinze, P Neville, Ferdinand, Silvestre, Bellion, Keane, Ronaldo, Scholes, Fletcher, Miller, Giggs, Smith, Richardson, Djemba-Djemba
