Vidic Out For The Season?

During today's Mancherster United-Blackburn (4:1) game, Nemanja Vidic was attempting to win a header, however he lost his balance and fell on his collarbone. It is very possible that he broke his collarbone and that he will be off the field for a few months. This will give a headache to both Sir Alex Ferguson (Man U) and Javier Clemente (Serbia's coach) as he is an indispensible player. For Manchester United O'Shea might be able to play in Vidic's position. However, Serbia has no direct replacement for Vidic. Since Serbia has no direct replacement if I was Javier Clemente I would give a chance to a young Slobodan Rajkovic (OFK Beograd-Chelsea) who has similar style like Vidic. Lets wait and see what happens.
