Pittsburgh has been outscored 17-11 in the three losses, the past two without goalie Matt Murray, who sustained a concussion during practice Monday. Murray will miss his third straight game, though he skated on his own Friday and Saturday but didn't take shots.
Pittsburgh is in third in the Metropolitan Division, two points behind the second-place Philadelphia Flyers and three behind the first-place Washington Capitals.
New York, which is four points behind the Columbus Blue Jackets for the second wild card into the Stanley Cup Playoffs from the Eastern Conference, is 0-4-1 in its past five games, including a 6-3 home loss to the Montreal Canadiens on Friday. This is the first of a four-game road trip; the Islanders play their next three games in Western Canada.
