AVALANCHE 2, MAPLE LEAFS 1
TORONTO (AP) — P.A. Parenteau scored early in the third period to help Colorado edge Toronto.
Tied 1-1 going into the third, Colorado went ahead at 2:30 on a two-on-one with Jamie McGinn setting up Parenteau.
The goal stood up to video review.
"According to Rule 78.4 'if an attacking player has the puck deflect into the net, off his skate or body, in any manner, the goal shall be allowed.' Good goal Colorado," the NHL said in explaining the call.
Avs rookie Nathan MacKinnon, the 18-year-old first overall pick in the draft, got an assist — his fourth — on Parenteau's third goal of the season. Cory Sarich also scored for Colorado, which got another terrific start from Semyon Varlamov in net.
Joffrey Lupul scored for Toronto.
ISLANDERS 6, COYOTES 1
Frans Nielsen earned the second of his three assists on the night when McDonald made it 5-1 with 2:36 left in the second.
Evgeni Nabokov was the beneficiary of all the offence and made 33 saves for the win. The 38-year-old goalie has started all three games for the Islanders.
Martin Hanzal scored in the second period for the Coyotes.
FLYERS 2, PANTHERS 1
Berube was on the bench a day after Peter Laviolette was fired after a 0-3 start.
With Berube calling the shots, the Flyers scored their season high for goals.
Steve Mason had 33 saves for the Flyers.
Brad Boyes scored for the Panthers.
LIGHTNING 3, SABRES 2, OT
BUFFALO, N.Y. (AP) — Alex Killorn scored 2:50 into overtime to lift Tampa Bay to a come-from-behind victory over winless Buffalo.
Tampa Bay has yet to hold a lead in regulation after coming off a 3-2 shootout victory at Chicago in which the Lightning overcame a 2-0 third-period deficit.
Despite the loss, Buffalo finally generated some offence by doubling its season goal total. And the Sabres also earned a point to avoid extending their franchise-worst season-opening losing streak to four games.
Buffalo had previously never lost more than two straight in regulation.
