Defenseman Kevin Klein will make his season debut for the New York Rangers after missing the first three games because of back spasms. Klein skated with defenseman Ryan McDonagh and Rangers extras at an optional morning skate. "You go through preseason and play the preseason games and you're excited to get in there," Klein said. "Now I haven't played a game for two weeks. I'm really excited every year opening up. The home opener with the boys, I missed that, but this is mine, so I'm happy." Defenseman Dylan McIlrath will be a healthy scratch. Coach Alain Vigneault said it's a numbers game at this point of the season. McDonagh will play after missing practice Tuesday because of the birth of his first child, Falan Erin. He learned his wife's water broke following the Rangers' 7-4 win against the San Jose Sharks on Monday, went home to change and headed to the hospital. "Everything went smoothly, everybody is fine. Pretty excited to say the least," McDonagh said. "It should be the first thing on my mind as soon as I step out of the rink and it will be really fun just to see her grow up."
