Rangers forward J.T. Miller had almost as short a night as Lundqvist. The Rangers' third-leading scorer with 29 points (10 goals, 19 assists) in 49 games was benched for the second and third periods after his first-period giveaway helped lead to Ducks center Adam Henrique's shorthanded breakaway goal at 18:38, making it 4-2.
Rangers coach Alain Vigneault was terse when asked about the reason behind Miller's benching. "I'd seen enough," he said.
The injury-riddled Rangers (24-20-5), who began the night in position to make the Stanley Cup Playoffs, fell two points behind the Pittsburgh Penguins for the second wild card from the Eastern Conference.
Lundqvist, their all-star goalie, has 21 of the Rangers' 24 wins, but his excellence may have masked some of their deficiencies. They are 2-6-0 since Jan. 7.
"Obviously right now we need the points," Lundqvist said. "There no question about it. We have one more game before the (All-Star) break and we just have to do whatever we can to get points."
There's been little good news for the Rangers since it was announced Friday that defenseman Kevin Shattenkirk (torn meniscus) needed left knee surgery and will be out indefinitely.
How the Rangers respond to his absence could shape how management approaches the NHL Trade Deadline on Feb. 26. Should they continue to lose ground, they could turn into sellers at the deadline, especially with forwards Nash and Michael Grabner (21-4-25 in 48 games) set to become unrestricted free agents July 1.
This important four-game road trip has not gone well. The Rangers have been outscored a combined 13-6 in losses at the Colorado Avalanche, Los Angeles Kings and Ducks. They allowed three power-play goals in a 4-2 loss to the struggling Kings at Staples Center on Sunday and several mistakes led to their unraveling against the Ducks.
"It's been intense here the last week," Lundqvist said. "You battle through it. You're not going to feel great starting every game. It's just part of playing in this league. You've got to find a way to elevate your game and be on top of it, and tonight I wasn't."
