#Yes in Canon
In the animated series Star Wars Rebels (which is Canon according to Disney and Lucas), Season 2 double episode 1/2 The Siege of Lothal
When Darth Vader attacks the Ghost with Stormtroopers, he deflects shots made by Sabine, which hit her in her mandalorian helmet and knock her back
She seems perfectly fine after this.
(I can't at the moment look for a youtube video showing this scene. I would appreciate if anyone was willing to edit this answer and add a link to it.)
