Namestnikov was acquired by New York in a trade with the Tampa Bay Lightning on Monday and joined the Rangers in Vancouver late Tuesday, but the Rangers did not skate Wednesday morning.
New York traded defenseman Ryan McDonagh and forward J.T. Miller to Tampa Bay for Namestnikov and forward Brett Howden, defenserman Libor Hajek, a first-round pick in the 2018 NHL Draft and a conditional first-round pick in the 2019 draft.
The Rangers, 0-6-1 in their past seven games, are trying to avoid their longest skid since an eight-game losing streak (0-5-3) from March 12-25, 2004. New York is nine points behind the Columbus Blue Jackets for the second wild card into the Stanley Cup Playoffs from the Eastern Conference.
Forwards Brendan Leipsic and Tyler Motte each will make his Canucks debut after being acquired in separate trades Monday. Vancouver acquired Leipsic from the Vegas Golden Knights in for defenseman Philip Holm. Motte and forward Jussi Jokinen were acquired from the Columbus Blue Jackets for forward Thomas Vanek.
Vancouver is 3-8-1 in its past 12 games and 19 points behind the Anaheim Ducks for the second wild card into the Stanley Cup Playoffs from the Western Conference.
