Just when the Rangers were starting to find their game, winning seven of their last nine contests, crawling out of that large hole they dug for themselves, comes this: Ryan McDonagh, their most valuable player not named Henrik Lundqvist, their captain, will miss a game Wednesday against the Hurricanes. The Rangers have termed it an abdominal strain, and offered very little details otherwise. McDonagh didn’t practice Tuesday, and won’t even travel with the team to Raleigh, N.C. He will see team doctors, and more information will be offered Wednesday, according to Rangers coach Alain Vigneault. His absence from practice this year on occasion, described as “maintenance days,” was the result of the abdominal strain he’s now dealing with. “It’s something that has been there for a little bit, doesn’t seem to be getting better right now,” Vigneault said. “So we just want to check it out. I’ll have more for you tomorrow.” When asked if McDonagh would be out for longer than a game, Vigneault said he had “no idea.” “I just know it’s been bothering him,” the coach said. “It’s been lingering a little bit. We want to double check things.” Steven Kampfer, a healthy scratch the last two games, will replace McDonagh in the lineup. Vigneault will keep the Brady Skjei-Kevin Shattenkirk pairing together. Kampfer will be paired with Marc Staal, and Brendan Smith with Nick Holden.
