Edit: Khudobin was traded by the Wild to the Boston Bruins in February 2011. He's been playing for their AHL team in Providence. I have no information about or photos of his mask, so I can only assume he still has the same one.
*************************************
Khudobin played in 4 games in January for Minnesota following injuries to both Backstrom and Theodore.
He said in the past he has angels on his mask because "Angels kind of help people. When I was trying to think of what to do, I didn’t know what team I would be on so I can’t put a special logo like Minnesota Wild or Houston Aeros.”
I don't have great photos yet, but here's what I've found.
And Khudobin got his first career NHL shutout tonight against Vancouver.
