DENVER (AP) — Ukko-Pekka Luukkonen made 40 saves, Tage Thompson had a goal and two assists and the Buffalo Sabres beat the Colorado Avalanche 4-2 on Thursday night.

Rasmus Dahlin had a goal and an assist, Alex Tuch also scored for Buffalo and Tyson Jost had an assist in his first game in Denver against his former team. Jost, who was dealt to Minnesota at the trade deadline last season, got an ovation from the fans after a scoreboard video highlighted his five-plus years with the Avalanche.

Mikko Rantanen and Evan Rodrigues scored for Colorado, with Rodrigues back after missing nine games because of a lower-body injury.

Alexandar Georgiev allowed two goals on the first three shots he faced and finished with 17 saves. The Avalanche had their two-game winning streak snapped.

Thompson stayed hot with his 24th goal of the season, just 54 seconds into the game. He has three goals and three assists in the last two games, and had five goals and an assist Dec. 7 in a victory at Columbus.

They added another on the power play when Tuch scored on a rebound at 7:08 of the first, his 15th of the season, to make it 2-0.

Colorado outshot Buffalo 12-8 in the second period but the Sabres got the only goal when Dahlin’s wrister from the slot beat Georgiev with 2:49 left.

The Avalanche pressed for a goal after the second intermission and finally broke through at 8:20 when Rantanen scored his 20th on an odd-man rush with Valeri Nichushkin.

Colorado pulled Georgiev for an extra skater with 3:07 left and Rodrigues scored with 1:22 to go. Cozens scored an empty-netter with 58 seconds left.

Pavel Franouz was under the weather, according to the Avalanche. … Colorado has failed to score on its last 17 power-play chances.
