McNair started Northern Ireland’s 1-1 draw with Finland but was forced to come off with what, at the time, seemed like an abdominal injury. Further tests showed that the youngster had ruptured his liver and was forced to remain in hospital for three days.
The centre-back has now been cleared to return to Manchester, where the club’s doctors are set to assess his injury and determine how long he could be unavailable for. Initial reports suggest that McNair could be out for a minimum of two weeks as he recovers from his injury.
The 20-year-old made his breakthrough into Man United’s first team last year, when a defensive crisis meant he had to be deployed at centre-back for the visit of Everton last season. Now, as United prepare to make the trip to face the Toffees, McNair will be disappointed with the timing of his injury.
After completing 90 minutes for his national side in their 3-1 victory over Greece, McNair would have felt he was closing in on more opportunities at United.
However, he is forced to rest for two weeks instead and will have no part to play in a critical game for United. McNair will want to recover as quickly as possible and hope that his experience with Northern Ireland helps him to register more regular playing time at United and the chance to shine at first-team level.
