What to watch: Hawks coach Joel Quenneville said Tuesday that Brent Seabrook (leg) and Michael Frolik (shoulder) would be game-day decisions. Seabrook missed the last three games but returned to practice Tuesday and was paired with Duncan Keith. The Sharks are just 2 points behind the Hawks in the Western Conference standings after winning their last three games and seven of the last 10 (7-2-1).
