The Tampa Bay Lightning have the visiting Montreal Canadiens down and can deliver the knockout punch when the teams square off Thursday in Game 4 of their Eastern Conference semifinal series. The Lightning took a commanding 3-0 lead in the best-of-seven matchup with a last-second goal in Wednesday's Game 3 and look to avenge a sweep by Montreal in last year's postseason with one of their own.

The Chicago Blackhawks attempt to complete their first sweep of a playoff series in five years when they visit the Minnesota Wild for Game 4 of their Western Conference semifinal matchup on Thursday. After needing six games to get past Nashville in the first round, Chicago is on the verge of eliminating Minnesota in the minimum amount of contests required and advancing to the conference final for the fifth time in seven postseasons.
