Smalling suffers Euro 2012 woe

Manager Sir Alex Ferguson confirmed the news on Friday morning after Smalling suffered the injury during last week's win over Swansea at Old Trafford.

"Chris has suffered a bad injury," said Ferguson. "It is a groin muscle injury and he will miss the European Championships.

"We are assessing what to do at the moment but it is a bad injury."

Smalling has won three caps for England, the most recent of which came in a friendly defeat to Netherlands at Wembley in February.

Ferguson also confirmed Danny Welbeck would be available for this summer's tournament, even though he will miss Sunday's trip to Sunderland with an ankle injury.

"He is still out just now but he should be fit for the Euros," Ferguson said.

Ferguson said Phil Jones would replace Smalling at the Stadium of Light, where United, if they are to win the Premier League title, must win and hope Manchester City fail to beat QPR in their final game.

Ferguson said: "We can only do our best and try to win the game, and hope something stupid happens to Manchester City."

England have lost Jack Wilshere to injury for the finals in Poland and Ukraine and are also awaiting news of whether ankle ligament damage will prevent Darren Bent from joining up with the squad.

The striker has not played for Aston Villa since February.
