Man. United Await Vidic Scan Verdict

Manchester United defender Nemanja Vidic will have a scan on his knee on Wednesday after being carried off in the 2-0 Champions League win over Roma.

Centre-back Vidic fell awkwardly during the first half in the Stadio Olimpico and despite sustained treatment had to be replaced by John O'Shea.

"I pray it's not serious because he is such an integral part of our team," said United manager Sir Alex Ferguson.

"It might just be a nerve injury but we can't be sure at this moment."

Vidic has formed a superb partnership with Rio Ferdinand at the heart of the United defence and any lengthy absence would be a huge blow as they target a Premier League and Champions League double.

O'Shea stepped in alongside Ferdinand in Rome, while Mikael Silvestre returned to the senior squad for the first time since September after recovering from a knee ligament injury.
