"We're still trying to figure out exactly how serious it is," Blackhawks coach Jeremy Colliton said Saturday. "But he didn't skate today."
Lehner required attention from a Blackhawks trainer after he got tangled up awkwardly with Canucks forward Tanner Pearson with 4:57 left in the third period. Lehner finished the game and had an ice bag on his right knee afterward, but he said the injury wasn't serious.
Lehner is 12-7-4 with a 2.92 goals-against average and .922 save percentage this season, his first with Chicago after signing a one-year, $5 million contract July 1.
Corey Crawford (6-11-2, 3.20 GAA, .905 save percentage) is expected to start when the Blackhawks host the Detroit Red Wings on Sunday (7:30 p.m. ET; NBCSN, NHL.TV). It will be Crawford's first start since he allowed four goals on 20 shots in 30:40 and was pulled in a 7-1 loss to the New Jersey Devils on Dec. 23.
"I mean, the [New] Jersey [game] was obviously a rough one," Crawford said. "I don't think I've been playing bad. I've just got to make that extra big save. I don't know. Just got to keep going, keep working hard.
"I definitely think I can still make an impact. But [Lehher has] been playing great, so [Colliton's] choice was to stick with him and we got some big wins. For me, it's just to stay ready and obviously I've got a chance here, so I'm just trying to be ready."
Colliton wasn't concerned that Crawford could be rusty after not playing in nearly two weeks.
"He'll be ready," he said. "He's been working hard in practice, he's been great in practice and he's been good for us this year. We're excited to see him react to the opportunity."
The Blackhawks (18-18-6) recalled goalie Kevin Lankinen on an emergency basis from Rockford of the American Hockey League on Saturday.
