NHL: 5 things to watch on Tuesday night

Here are a few things to monitor on a busy Tuesday night in the NHL:

Reimer over Bernier

Fans can stop worrying about another potential concussion for James Reimer, who will start in goal for the Toronto Maple Leafs against visiting Colorado (7 p.m. ET).

Two nights ago, Reimer was forced to leave his team’s 6-3 win in New York after Rangers forward and ex-Leaf Dominic Moore clipped him while skating through the crease. After the game, Reimer told reporters he was fine and that appears to be the case.

Reimer looked solid against the Rangers, stopping 24 of 26 shots. He’s more locked in early in the season than supposed No. 1 netminder Jonathan Bernier, who sports a 4.55 goals-against average and .882 save percentage.

Matt Duchene, Jarome Iginla, Nathan MacKinnon, Gabriel Landeskog and Ryan Reilly have yet to score for 1-2-0 Colorado but it’s only a matter of time before they fill the net consistently.

In need of AHL seasoning?

Much of the pre-season in Calgary was spent discussing the likelihood of forward prospects Sam Bennett and Johnny Gaudreau breaking training camp with the team. Well, Bennett is prepping for shoulder surgery while Gaudreau will be looking for his first point Tuesday when the Flames visit Nashville (8 p.m. ET).

Gaudreau, last year’s Hobey Baker Award winner as the top player in U.S. college hockey, has just one shot but maybe facing the vaunted Predators defence will be the challenge “Johnny Hockey” needs. The 21-year-old played for Nashville coach Peter Laviolette earlier this year at the world hockey championship for Team USA.

Trio on the limp

The Edmonton Oilers pay a visit to the reigning Stanley Cup champion Kings in Los Angeles (10:30 p.m. ET) and might find themselves significantly undermanned as forwards Ryan Nugent-Hopkins, Jordan Eberle and Ted Purcell are nursing undisclosed injuries. Purcell shares the team scoring lead after three games with David Perron.

Shutout watch

Can the Pacific Division-leading San Jose Sharks manage a third consecutive game to open the season without allowing a goal? Antti Niemi shut out Los Angeles in the season opener and Alex Stalock blanked Winnipeg, so the open competition for the No. 1 job is off to an exciting start. The Sharks are visiting Washington, where Braden Holtby has one shutout in two starts this season.

Battle of New York

Brock Nelson, yes, Brock Nelson of the New York Islanders will try to move atop the NHL scoring lead. His six points tie him with Sidney Crosby, whose Pittsburgh Penguins are idle. Islanders defenceman Johnny Boychuk is paying immediate dividends following a recent trade from Boston with a goal and five points.

The 2014 Cup finalist Rangers have dropped back-to-back games against Columbus (5-2) and Toronto (6-3).

Other notes:

- Anaheim’s Corey Perry (four goals in three games) looks to feast on 0-3-0 Philadelphia, which will be minus forward Vinny Lecavalier (lower-body injury) for two weeks.

- Dallas’ star forwards Jamie Benn and Tyler Seguin will try to get out of their early-season funks (pointless and minus-3 in two games) in Columbus.

- Buffalo (0-3-0) or Carolina (0-2-0) will record its first victory of the season as they meet in Raleigh, N.C.
