Off The Draw: Tragedy in Ottawa; Voynov ban will cost Kings

The NHL has canceled Tuesday night's game in Ottawa due to a series of tragic shootings; Slava Voynov's suspension and cap hit will haunt the Kings, tonight's must-see games, more notes.

What you missed last night:

NHL postpones Senators vs. Maple Leafs in wake of Ottawa shootings

• The Rangers' Rick Nash continued to light it up.

• Anaheim sits atop the first edition of our Power 10, but the Ducks weren't a unanimous choice.

• Alex Pietrangelo got a new haircut from his niece—the Blues D-man is supporting cancer awareness.

• Islanders defenseman Thomas Hickey became the latest player to get zipped up after taking a skate to the face.

• The Sabres will retire Dominik Hasek's No. 39 in a ceremony before taking on the Red Wings.

• Blackhawks goalie Corey Crawford is sidelined with a dreaded upper-body injury.

What to watch tonight:

Maple Leafs at Senators (7 p.m. EDT; TVA, SN1)

UPDATE: Due to today's tragic shooting incidents in and around Canada's Parliament building in Ottawa, this game has been postponed. The Maple Leafs are in lockdown at their hotel near where one of the shootings was reported. Events are still unfolding, but one gunman and a Canadian soldier have been killed, and a parliament guard was wounded.

The Maple Leafs are coming off an impressive road win on Long Island and the Senators have taken four straight, but both teams are displaying an  tendency to let their opponents take offensive liberties. At 34 and 35.6 shots-allowed per game respectively, they're both ranked among the bottom seven in the league. That's going to put all the pressure on the keepers tonight. James Reimer is expected to get the start for Toronto after Jonathan Bernier backstopped the Leafs to their 5-2 win over the Isles last night. Reimer's numbers aren't great (.906, 2.87), but he's won two of three and he's been lights out against Ottawa during his career (9-2-1 with a .944 save percentage and 1.98 GAA). Coach Paul MacLean hasn't said who'll start for the Sens, but Robin Lehner was strong on Saturday, stopping 38 shots to bump his save percentage to a sterling .950 in two appearances this season.

Flyers at Penguins (8 p.m. EDT; NBCSN, TVA2)

This may have been a rivalry last season but it wasn't much of a contest—the Flyers won all four meetings against their cross-state foes. If they want to keep that streak going, the formula is simple: keep Pittsburgh's top two lines off the board. If the Flyers can manage that trick, they're golden. Pittsburgh's third and fourth lines are struggling to contribute anything offensively, managing just one goal and three points in the early going. Lack of depth killed the Pens last season. Is that going to be a problem again in 2014-15? It might help that the Penguins are playing against a Philly defense that's been nothing more than a rumor during the Flyers' past couple of games. They coughed up 43 shots in a non-compete performance against the Blackhawks on Tuesday night, an ugly effort after a series of blown coverages in Dallas allowed the Stars to score five on netminders Steve Mason and Ray Emery on Saturday. GM Ron Hextall is beating the bushes for a veteran defenseman with some shutdown potential but he's stuck with this easily exploitable group for now.

Sabres at Ducks (10:30 p.m. EDT; MSG-B, BELL TV, PRIME)

The league's top team against the worst. This should be fun. Buffalo coach Ted Nolan said the Sabres “looked like a pee wee team” in their 5-1 loss to Anaheim last week, which may have been more insulting to pee wees than his own players. You have to think the sting of that no-compete loss will provide some motivation, but will that be enough? Probably not. The Sabres have scored just seven goals in six games, with four players—Tyler Ennis, Marcus Foligno, ZemgusGirgensons and Torrey Mitchell—accounting for all the scoring. It's about time for newcomers Matt Moulson and Brian Gionta to get off the schneid, right? The two veterans, who were brought in specifically to add scoring depth, have combined for two assists during their sluggish starts. If this team has any hope of being competitive, it's on those guys to not just set an example in the room, but to start lighting the lamp with some frequency.

• Coveted prospect Connor McDavid plays in Buffalo tonight

The rest of the schedule:Capitals vs. Oilers (9:30 p.m. EDT; SN360, SN1, CSN-DC)

Today's must-reads:

• Columbus winger Nathan Horton has been diagnosed with “degeneration” of the entire lumbar region of his spine—his lower back. I'm no doctor, but that doesn't sound good.

• I'm with Kevin Kurz. Despite his solid point production, Brent Burns has been a disaster on defense for the San Jose Sharks. It's only a matter of time before this experiment is shelved.

• The L.A. Kings are rallying around each other as they try to compensate for the loss of top-four defenseman Slava Voynov.

• Terrific piece here from Chris Johnston on the salary cap implications of Voynov's suspension. For a team that's less than a million bucks under the ceiling, the impact of a prolonged suspension on the Kings could be substantial.

Boston's burly winger, who infamously uttered a death threat at the Canadiens' Dale Weise in the handshake line after their playoff series last spring, was feeling all warm and fuzzy when the teams met for the first time this season in Montreal on Oct. 16. Along with this bout against Alexei Emelin, Lucic was fined $5,000 by the NHL for making a lewd gesture at the Habs' faithful after he took a penalty in the Bruins' loss. He later apologized.

The red-hot Nash became a Broadway Smash by scoring seven goals in his first six games. One tally came four seconds after teammate Martin St. Louis lit the lamp against San Jose, the duo setting a franchise mark for fastest goals without an empty-netter.

Some wags suggested that it's only apt that the Maple Leafs, who currently own the NHL's longest Stanley Cup drought by a non-expansion team, employ a giant deodorant to resurface the ice in their home arena. The Leafs lost their first two games at Air Canada Centre en route to a 2-3-1 start.
