It has been known for a while that Niall has had a problem with his knee, and the constant tour dates are only putting more strain on it.
The majority of fans have known that at some point Niall would have to have an operation on it to make it easier for him.
It turns out that Niall had the operation in America recently and has returned to the UK to rest up.
So you would think that having had an operation, fans would be incredibly supportive of Niall and wish him a speedy recovery.
However some were a bit upset that he didn’t tell fans about the surgery but still wished he would get well soon.
But one so called fan took it to a whole new level of weird, rude and giving directioners a bad name.
One idiot on twitter said: “Niall lied to us, he should of died in surgery. im gonna stop being a Directioner.”
Quite rightly this person was then subject to a lot of abuse from fellow Directioners.
Telling someone you supposedly adore/care for that they should have died, clearly shows that you weren’t a true directioner in the first place.
