Devils left wing Patrik Elias played 14:15 in his first game in four months. The 39-year-old, who was out with a right knee injury, is in the final season of a three-year contract and can become an unrestricted free agent July 1. There's a chance he could be playing his final games with New Jersey.
"I haven't played since [Dec. 19] and actually it wasn't that bad," Elias said. "Physically, it was fine. Hockey-wise, a little rusty on a couple of the plays passing and shooting, obviously, but overall not bad for first game back."
O'Reilly gave the Sabres a 1-0 lead on a power-play goal at 14:12 of the second period. After a pass from Eichel in the right circle, O'Reilly scored his 21st with a slap shot that beat goalie Cory Schneider to the glove side.
"The coaching staff has been harping on having more of a shot mentality and that [O'Reilly] goal was a great example," Bylsma said. "It was a great read by Jack on the seam pass to get it to Ryan and there was no doubt about the shot."
Larsson made it 2-0 12 seconds into the third period when he scored an unassisted goal with a wrist shot from the right circle that beat Schneider on the long side.
