The team took it day-by-day, game-by-game, listing him as questionable for every contest. The 28-year-old hadn't missed three games in a season since the 2013-14 season, when he missed eight. This season, he has recorded four goals and eight assists in 21 games.
Meanwhile goalie Corey Crawford is out indefintely after undergoing an appendectomy this weekend. The procedure took place on Saturday, forcing him to miss a scheduled start against the Flyers.
The 31-year-old had started in 20 of Chicago's 25 games this season, going 12-6-2 with a 2.27 goals-against-average, .927 save percentage, and two shutouts. He ranks second in the NHL in wins on the year.
The team placed Scott Darling to start against the Flyers, and he allowed three goals on 30 shots in a 3-1 loss. Darling is 4-1-1 on the year, and is now the Blackhawks' number one goalie.
Crawford is a two-time Stanley Cup winner, leading the Blackhawks to Stanley Cups in 2013 and 2015.
