Blackhawks Havlat, Khabibulin are day-to-day
Chicago coach Joel Quenneville said both would be evaluated after Wednesday morning's pre-game skate.
Havlat returned to the Blackhawks' lineup Sunday, two days after he took a hit from Niklas Kronwall that forced him out of Game 3 in the first period.
Havlat, Chicago's leader in points during the regular season and in the playoffs, played only 7 minutes and 59 seconds Sunday and hardly at all after the first period.
Khabibulin left after two periods Friday with a lower body injury. Cristobal Huet replaced him Sunday and gave up five goals in a 6-1 loss.
