🚨 3-5!!! WHAT AN ABSOLUTE COLLAPSE! A nightmare ending for Avalanche fans as Colorado completely threw away a massive three-goal lead and watched the Golden Knights storm back in stunning fashion. From total control to total heartbreak — this shocking defeat felt like a brutal slap in the face for everyone inside the arena. The Golden Knights refused to give up and delivered one of the craziest comebacks of the season.

LAS VEGAS — For 20 minutes, the world-beating Colorado Avalanche made an appearance in the Western Conference Final.

Then a three-goal lead disappeared as quickly as it was created, another superstar was injured, and this once-dream season is officially on the brink.

The Vegas Golden Knights rallied after yielding the first three goals of this game, with Tomas Hertl providing the game-winner in a 5-3 victory in Game 3 of this best-of-seven series at T-Mobile Arena.

“It’s frustrating,” Avs star Cale Makar, who returned after missing the first two games of this series, said. “I mean, we’ve been on the other side of that, obviously coming back from that, and it’s going to happen. But it can’t happen at this time of the year. I felt like they got some lucky bounces, but we’ve got to find a little bit better way to kind of challenge ourselves in those moments and come out of that.

“Just unfortunate. We still had a chance, obviously, in the third there.”

Vegas leads the series 3-0. The Golden Knights can complete an absolutely stunning sweep of the Presidents’ Trophy winners on their home ice on Tuesday night.

To make matters worse, Avs superstar Nathan MacKinnon was injured blocking a shot during the second period. He tried to play through it after taking a hard shot from Shea Theodore off the outside of his right knee, but his mobility was clearly limited.

MacKinnon took one normal shift in the third period, then went on the ice for Colorado’s power play. His three even-strength shifts after the injury totaled a combined 88 seconds, and the Avs were without the NHL’s leading goal scorer this season while trying to come back until MacKinnon went out again for a 6-on-5 shift.

That shift ended with Brett Howden’s empty-net goal to seal the Vegas victory. MacKinnon still managed to play 4:05 in the third period, but that’s maybe 40 percent of what he’d play when healthy in this situation.

Avs coach Jared Bednar also noted that Valeri Nichushkin was injured in the third period. Nichuhskin took only one shift in the final seven minutes after Hertl’s goal with 7:14 remaining.

A tale of two periods

The first period couldn’t have gone much better for the visitors. The second period couldn’t have gone much worse.

Colorado blew a three-goal lead in less than 13 minutes. Vegas scored three times in the period on just eight shots.

The Golden Knights began the middle period on the power play. It took them 19 seconds to convert. Vegas captain Mark Stone, who returned after missing the past five games with an injury, tapped home a pass from Mitch Marner near the right post after a perfectly executed dump-in and retrieval.

William Karlsson made it a 3-2 game at 4:05 of the period. Marner shot the puck from the right point. Scott Wedgewood made the first save, but the rebound bounced off Parker Kelly’s stick and right to Karlsson, who whipped a shot inside the near post before the Avs goaltender could get square to him.

It was the first goal of the postseason for Karlsson, who is one of the original Vegas ‘Misfits’ from the inaugural season, but missed a huge chunk of this year before returning during the last round.

MacKinnon took a hard shot off the outside of his right knee with 7:54 remaining in the period. He was writhing on the ice for 9 seconds before play was stopped.

Keegan Kolesar tied this game at 3-3 on the next shift. Kolesar deflected a shot from the top of the zone by Dylan Coghlan off the right post and then tapped the rebound into the net for his first goal of this postseason.

Colorado’s offense roared to life at the start of this contest after two rough nights back home at Ball Arena.

Gabe Landeskog put the Avs in front just 3:21 into this contest. Devon Toews beat Noah Hanifin to a loose puck in the neutral zone, which created a 2-on-1. Hanifin took a penalty trying to defend Toews as he took the puck to the net, but Landeskog was there to put home the rebound.

That is five goals for Landeskog in the 2026 Stanley Cup Playoffs, just another chapter in his remarkable comeback story.

That was also Colorado’s first lead of the series. Nazem Kadri, moved up to the second line and to the wing for the first time in this postseason, doubled the advantage at 7:03 with one of the best team-effort goals of the season.

Josh Manson faked out Nic Dowd behind the Colorado net to free up space for the defenseman to hit Martin Necas with a tape-to-tape outlet pass beyond the red line. Necas split two defenders, then left the puck for Kadri, who buried a shot from the inside of the left circle for his third of the postseason.

Vegas thought it cut the lead in half during a Golden Knights power play. Pavel Dorofeyev batted the puck out of mid-air with a cross-checking motion near the edge of the Colorado crease. An official immediately waived off the goal, citing that Dorofeyev put the puck into the net with his hand.

After a lengthy review, the officials said the call on the ice was correct. Even if they had reversed it and awarded the goal, Colorado may have challenged for a high stick.

Either way, the Avs extended their lead to 3-0 just 43 seconds later. Parker Kelly backhanded the puck out of the Avs zone and two Vegas players missed it when trying to keep it in, leaving Jack Drury alone for a shorthanded breakaway. His deke fooled Vegas goaltender Carter Hart, and the Avs had a three-goal lead with 6:45 remaining in the opening period.

That lead was gone a little less than 20 minutes later. The season will end Tuesday night if the Avs can’t find a way to extend this series and get back to Ball Arena for a potential Game 5.
