United boss Sir Alex Ferguson must once again contend with massive defensive problems on Saturday. Jonny Evans (calf) has joined Nemanja Vidic (knee), Chris Smalling (tonsillitis) and Fabio (hamstring) on the sidelines. Phil Jones (illness) and Rio Ferdinand (back) only have an outside chance of being involved, which might mean Michael Carrick partnering Patrice Evra in central defence, with Antonio Valencia at right-back. Martin Olsson is hoping to make his long-awaited Blackburn comeback at Old Trafford. The Swede has featured just once for Steve Kean's men since November 5 after suffering a hamstring injury but could ease a major injury crisis for the Lancashire outfit. David Dunn and Junior Hoilett (both hamstring) face late tests but goalkeeper Paul Robinson (calf) is amongst seven senior players definitely out, as is Gael Givet, even though the Frenchman has returned to training following a minor heart procedure. United (from): De Gea, Lindegaard, Amos, Rafael, Ferdinand, Evra, Jones, Fryers, Cole, Carrick, Valencia, Park, Gibson, Nani, Giggs, Macheda, Rooney, Welbeck, Berbatov, Hernandez, Diouf. Blackburn (from): Bunn, Samba, Lowe, Hanley, Nzonzi, Rochina, Pedersen, Petrovic, Dunn, Hoilett, Olsson, Yakubu, Goodwillie, Formica, Roberts, Vukcevic, Slew, Blackman, Henley, Morris, Kean.
