Manchester United defender Rafael Da Silva has been ruled out of Manchester United's Champions League clash with Real Sociedad tomorrow.

The Brazilian suffered ankle ligament damage during United's win over Fulham on Saturday and went off injured at half-time in the game.

He is also a doubt for the Red's clash with table-topping Arsenal on Sunday.

David Moyes could play Chris Smalling or Phil Jones at right back for tomorrow night's match in the Basque country.
