The Chicago Blackhawks will once again have to deal with an existence without goaltender Corey Crawford, as he was placed back on injured reserve Wednesday. Crawford, who spent a week on I.R. earlier this season, has been one of the league’s best goaltenders, with a 16-9-2 record and a 2.27 goals against average this season in 28 games. He was yanked from his last start after giving up three goals against the New Jersey Devils, but had been strong prior to that game. To replace Crawford, the Blackhawks called up a pair of players, with goaltender Jeff Glass and forward David Kampf both recalled from the Rockford IceHogs.
