Five things to know about tonight's NHL games ...

1) Penguins, Bruins, Blackhawks and Avalanche can clinch. More playoff spots could be earned tonight depending on a number of scenarios, which you can find here.

2) Tuukka Rask looks out for TD Garden visiting locker room. Via the Boston Globe, Rask on the Blackhawks coming back to town since the infamous "17 seconds" game: “Probably brings some good memories to them. At least this time they’re not going to wreck our visiting locker room, I hope.”

3) Red Wings still waiting for Pavel Datsyuk. The "Magic Man" is still working back from a knee injury and doing everything he can to avoid having surgery.

4) Logan Couture 50/50 to play. After missing Tuesday's game in Edmonton, Couture is questionable to hit the ice against the Jets tonight. Couture was feeling the effects from a blocked shot and said he'll take the warmup before deciding whether or not he'll play.

5) Ted Nolan is a wise man:
