Mackenzie Blackwood is out indefinitely with a knee injury.
The goalie was injured in the second period after allowing two goals on 18 shots at the Edmonton Oilers on Nov. 3. Vitek Vanecek made 18 saves in relief for a 4-3 win.
"McKenzie has an MCL sprain and he'll be seeing doctors (Tuesday), and we'll get a further update on him," Devils coach Lindy Ruff said Monday.
New Jersey (9-3-0) has won six straight games for the first time since March 27-April 7, 2012.
Vanecek will make his second straight start when the Devils host the Calgary Flames on Tuesday (7 p.m. ET; MSGSN, SNW, ESPN+, SN NOW).
Akira Schmid
, recalled from Utica of the American Hockey League on Saturday, is expected to be the backup goalie.
Blackwood played 25 games (24 starts) last season because of a recurring left heel injury. He's 4-2-0 with a 2.79 goals-against average and .880 save percentage in seven games this season. Vanecek, acquired in a trade with the Washington Capitals on July 8, is 5-1-0 with a 2.21 GAA and .908 save percentage in seven games (five starts).
The Devils are home against the Ottawa Senators on Thursday and Arizona Coyotes on Saturday.
Goalie Jonathan Bernier (hip) hasn't played this season and remains on injured reserve.
"Right now, we're taking it one game at a time but really understanding that we will need a second goaltender," Ruff said. "We got Calgary tomorrow, then we have a day off, so I think we'll look at it after the day off where we're at and how Vitek is doing." -- Mike G. Morreale, staff writer
