Crawford, 35, has been absent since the Blackhawks returned to practice on July 13, with the team calling him "unfit to play." Bowman indicated Crawford can still get himself into a position in which he would be the Blackhawks' goaltender for their qualifying-round series opener against the Oilers in Edmonton on Aug. 1.
"At this point, nothing has been ruled out," Bowman said.
Further details on Crawford's absence and health status haven't been made clear. Under a collectively bargained return-to-play agreement during the coronavirus pandemic, NHL teams are prohibited from sharing medical information on players.
Crawford had a 2.77 goals-against-average and .917 save percentage in 40 games this season. Without Crawford, the Blackhawks have been preparing backups Malcolm Subban, Collin Delia and Kevin Lankinen as their goaltenders.
Until Crawford can return, the Blackhawks' focus will be on preparing their reserves, Bowman said.
"We still got a fair amount of time until Aug. 1 and the first game," Bowman said. "We're not thinking that far ahead right now.
"If and when Corey's ready, we'll have that conversation. But it's best to stick where we are today and not jump too far ahead."
