Matthews (upper body) will not be in the lineup versus Montreal on Thursday.
Matthews' upper-body injury has been classified as minor, but it's still just preseason, so the Leafs have no reason to rush him back into action. Given the number of veterans suiting up Thursday, it seems likely Matthews would have played had he been 100 percent. As of yet, there is no reason to worry Matthews won't be available to play versus Montreal on Oct. 9.
