Per the Free Press, Osgood will be back in goal while Maltby will be taking May's place in the lineup. May will be a healthy scratch. While I think May has played well lately, I'm not going to question Babcock's line juggling. With 3 games in 4 days, I think he knows what he's doing.
Also mentioned in the article is that Jimmy Howard will start in Montreal tomorrow night in large part because of his solid play there last season.
