Blackhawks goalie Corey Crawford will make his preseason debut on Friday against the Capitals. Chicago forwards Patrick Kane and Marian Hossa won't make their exhibition debuts until next week. "They know I need some games to get the timing and speed," Crawford said. "I don't know [how many]. Three or four should be good." Crawford, meanwhile, sat out Tuesday's 4-2 loss to Edmonton as Ray Emery and Alexander Salak split the game as they vie for the backup job.
