After one period, the Rangers and Jets are scoreless. That’s not the pressing concern for coach Alain Vigneault, who’s down to four defensemen. During the first, Ryan McDonagh and Kevin Klein left with injuries.

McDonagh sustained an injury on an Evander Kane hit. Kane finished his check sending McDonagh into the glass favoring his right shoulder. He skated off the ice with help from trainer Jim Ramsay. If it is indeed the shoulder he separated on an Alex Burrows hit, that could be significant.

Klein missed the rest of the period after getting hit by a puck early on. If he doesn’t return, Vigneault will lean heavily on Marc Staal and Dan Girardi. Both have been paired up since Monday. That leaves third pair Matt Hunwick and Michael Kostka together. For the Rangers, the forwards must forecheck to relieve pressure off a shorthanded D.

We’ll have more after the game.
