Blackhawks coach Jeremy Colliton said Crawford will not travel to Boston, where the Blackhawks play the Bruins at TD Garden on Tuesday (7 p.m., ET; NBCSN, SNE, SNO, SNP, TVAS, NESN, NBCSCH, NHL.TV), but that his full practice was a positive.
"He hasn't done that yet, so that's good," Colliton said.
Crawford is 6-14-2 with a 3.28 goals-against average, .902 save percentage and one shutout this season.
He missed 47 games last season and the first five games of this season with symptoms from a concussion he sustained against the New Jersey Devils on Dec. 23, 2017. He said he had some similar symptoms this time but is grateful that he's feeling better much sooner.
"Just try to be patient, try to be confident that it won't last long and it's been nice that it's back to normal," Crawford said. "I'll just keep going. Hopefully nothing trickles back and I can just feel good from here on."
Goalies Cam Ward and Collin Delia have shared duties with Crawford sidelined. Ward is 11-8-4 with a 3.67 GAA and .895 save percentage in 24 games this season. Delia,
who agreed to terms on a three-year contract
with the Blackhawks on Monday, is 6-2-3 with a 2.98 GAA and .923 save percentage in 12 games.
Chicago (23-24-9) has won seven straight games and is four points behind the Minnesota Wild for the second wild card into the Stanley Cup Playoffs from the Western Conference.
