Sorry for the shit sources.
From the Sun:
And asked whether he needed an operation,
Man Utd ace Rashford, 23, said: “I have to decide after - it's either an operation or I don’t get an operation on my shoulder.
“I’m not 100 per cent sure if I need it yet. I’ll finish strongly here and like I said I’ve got a few weeks off to just relax and decide what I’m going to do.
“The doctors have not said how long I’d be out for.

And from the Telegraph:
Marcus Rashford may need shoulder surgery after European Championship
Manchester United striker suffered muscle tear in his left shoulder against Arsenal in November and problem has yet to correct itself

If it's rotator cuff surgery, that could mean he's out for months. Can anyone more knowledgeable chip in?
