Blackhawks defenseman Brent Seabrook left Sunday's 6-3 win against the Oilers in the second period after falling down hard against the end boards. Seabrook limped off the ice favoring his left leg and headed for the dressing room. The Hawks declared him out for the rest of the night due to a "lower-body injury." "(Brent Seabrook is) day to day right now," Blackhawks coach Joel Quenneville said after the game. "We'll know more in the morning. We'll see how he presents."
