Paddy McNair has joined Manchester United's injury list.
The Daily Mail says the teenager is understood to have suffered a hamstring injury in Sunday's win over Everton.
McNair, 19, has started the last two games in central defence because of injuries to Jonny Evans, Phil Jones and Chris Smalling.
But after he was called up by Northern Ireland on Monday in place of Evans for the Euro 2016 qualifiers against the Faroe Islands and Greece, it emerged that McNair was unable to join up with Michael O'Neill's squad because he could be out for up to three weeks.
