Vidic out for 2-3 weeks Nemanja Vidic has been ruled out for two or three weeks with a knee injury. The Serbian centre-back, who fell awkwardly after an aerial challenge against Roma, came off after just 31 minutes of Tuesday's 2-0 quarter final first-leg win. He was sent for a scan on Wednesday, the results of which showed the injury not to be serious. A club spokesperson told ManUtd.com: "There is no major damage to the left knee, and Nemanja will be out for around 2 or 3 weeks." Vidic will therefore miss the Premier League matches against Middlesbrough and Arsenal and Wednesday's Champions League quarter final second leg clash with Roma. He could return to face Blackburn Rovers at Ewood Park on 19 April, and will certainly hope to be involved should United reach the Champions League semi finals, before the Reds visit Chelsea on 26 April.
