Hayes tweaked his shoulder in Friday's game against the Blackhawks and will not be available for the Rangers' preseason finale Saturday vs. the Devils, Andrew Gross of the Bergen Record reports. Hayes apparently suffered the injury when he checked a Blackhawks player, with coach Alain Vigneault labeling him day-to-day. The forward still remains in the mix for a roster spot, but he'll be replaced in Saturday's lineup by Chris Kreider.
