Jarvis scored at 2:10, just seven seconds after Buffalo defenseman Owen Power was penalized for tripping Carolina forward Logan Stankoven. Jarvis capitalized on a sharp-angle rebound after Ukka-Pekka Luukkonen stopped his shot from the right hash marks.
Andrei Svechnikov had a goal and an assist, and Brandon Bussi made 17 saves for the Hurricanes (31-15-4), who have won three in a row and are 7-1-1 in the past nine games. Sebastian Aho had two assists.
Rasmus Dahlin scored, and Luukkonen made 26 saves for the Sabres (26-17-5), who have lost their past two games (0-1-1).
Dahlin gave Buffalo a 1-0 lead at 1:33 of the first when he gathered the puck at the red line, skated the puck into the offensive zone and scored on a snap shot from the right face-off circle over Bussi’s glove.
Svechnikov tied it 1-1 at 7:04. After Sean Walker forced a turnover in the neutral zone, Aho skated to the right circle before making no-look pass to Svechnikov for a backdoor tap-in at the left post.
Bussi kept the game tied with a highlight-reel save at 8:29 of the second period, lunging across the crease to glove Tage Thompson’s one-timer during a 2-on-0.
