Romelu Lukaku was stretchered off with a head injury against Southampton

Manchester United striker Lukaku went up for a header with Wesley Hoedt after just nine minutes.

The Belgian received a blow to the back of the head after winning the ball.

He received treatment from medical staff on the field and was given oxygen.

Lukaku was eventually stretchered down the Old Trafford tunnel as fans from both sides gave him a standing ovation.

He was treated at Old Trafford and Jose Mourinho told MUTV that he expects his No.9 to be sidelined for at least two games.
