Coyotes Head Coach Dave Tippett on Tuesday said starting goalie Mike Smith is day-to-day with a lower-body injury.
Smith was injured in the third period of Phoenix's 4-3 overtime loss to the New York Rangers on Monday night when Rangers forward Derick Brassard fell on him.
"He had some tests done this morning and... he'll be evaluated by our doctors when we get home (on Friday)," Tippett said.
The Coyotes play at Pittsburgh on Tuesday and at New Jersey on Thursday.
Smith started his League-high 61st game Monday. He's 27-21-10 with a 2.64 goals-against average, .915 save percentage and three shutouts.
Tippett said backup goalie Thomas Greiss originally was scheduled to start Tuesday so there will be no disruption to the team's plans.
Greiss said he's not looking beyond tonight's game, his first start since Feb. 28.
"I was scheduled to play this game anyway, so (I'll) just focus on that and worry about that for now," Greiss said.
Tippett said he's confident the Coyotes can succeed despite temporarily losing their starting goalie.
"We got good leadership in this that room," Tippett said. "They'll be ready to go. We're in a hard playoff hunt right now. Every game is important, doesn't matter who you play. We did some good things in that game (on Monday) that we have to build on. Take some of the mistakes out. That's the mindset we have. … We've got to put our work boots and find a way to win."
In response to Smith's injury, the Coyotes on Tuesday recalled goalie Mark Visentin from the American Hockey League. Phoenix chose Visentin 27th overall at the 2010 NHL Entry Draft. He is 14-19-10 with a 3.30 GAA and .901 save percentage in 44 AHL games.
