No-one does, but there is a big air of unprofessionalism about it.
He randomly turned up in the UK a week ago when one of the clubs announced he was training with them. Cue confusion. Then he failed to let the organisers know (despite having a week to do something about it) and was included in the main draw, only to be replaced by a lucky loser hours later.
Doesn't look very good from Evans' point of view.
He seems to be going off the rails again, which is disappointing.
