McElhinney was called up when Mike Smith was injured in December, and he came into the game in relief of LaBarbera on 12/26/11. I have no official photos yet. These are just screen captures, but I can tell it's different than what he wore in training camp.
During training camp, McElhinney was wearing his Ottawa mask from last season (which was also his Calgary mask previously.) Which is fine by me, because it was one of my favorites from last season.
Edit: As Scott pointed out in the comments, this mask is the same as last season, but he's using a different cage (the same one as Tim Thomas.) I'll post a photo from last season below.
