Manchester United boss Sir Alex Ferguson has been handed more defensive headaches after last night's 2-2 draw with Porto.

Rio Ferdinand is almost certain to miss Saturday's trip to Sunderland with the groin injury which sidelined him last night.

He will be joined on the sidelines by Jonny Evans, who limped off midway through the second-half and now faces a rush to be fit for the second leg next Wednesday.

"Rio was nowhere near being fit tonight, so it is difficult to see him being fit for Saturday," said Ferguson.

"Jonny should be okay in a week but he is a 21-year-old lad and this is what happens when you play two big games in three days."
