Zlatan Ibrahimovic landed awkwardly near the end of regulation in the Europa League quarter-final second leg against Anderlecht, and a bad injury was feared as he had to be taken off for extra time.
The 35-year-old limped off the pitch and manager José Mourinho stated after the game that he thought the news was "fairly negative". Luke Shaw, however, is more optimistic.
"He's fine. He was walking around in the changing room," the left-back told reporters after the game.
Marcus Rashford went on to score an extra-time winner for United, who advanced to the semi-final over Anderlecht after a 3-2 win on aggregate.
