BOSTON (AP) – Lukas Dora scored the game-winner with 11:35 left Thursday as Denver rallied from a two-goal deficit to beat Minnesota Duluth 5-3 in the NCAA hockey semifinals and advance to the Frozen Four championship game.

Denver trailed 2-0 and 3-1 before getting four consecutive goals – the first two when Gabe Gauthier and Ryan Caldwell scored 34 seconds apart to tie it just 3:04 into the third period.

Five minutes later, Dora skated across the ice and fought off a defender to slip the puck between Isaac Reichmuth’s pads.

Adam Berkhoel stopped 26 shots for Denver (26-12-5), which will play for its first championship since 1969 on Saturday night against the winner of the late semifinal between Boston College (29-8-4) and Maine (32-7-3).

The Western Collegiate Hockey Association foes had already played twice this season, with Duluth winning both games back in January.

Junior Lessard scored two power-play goals, and Reichmuth made 25 saves for Minnesota Duluth (28-13-4). He was pulled for the last 1:25; Duluth knocked one in with 32.2 seconds left, but the goal was disallowed because Tyler Brosz was in the crease before he barreled into the goaltender and dislodged the puck.

Greg Keith added an empty-netter with 7.8 seconds left to clinch it.

The leading scorer in the nation with 32 goals and 63 points, Lessard is one of three finalists for the Hobey Baker Award that will be given to college hockey’s top player Friday. He is the only one of the three who made it to the Frozen Four as a player, too.

Lessard opened the scoring just 1:09 into the game when he took a pass from behind the net and – with one skate on the goal line – two-handed into the upper corner of the net to make it 1-0. Brosz made it 2-0 just 3:25 later when he got a pass from the face off and wristed it under the leg of a defender, off the post and into the net.

Denver didn’t muster much offense until Luke Fulgham poked a rebound through Reichmuth’s pads with 8:20 left in the second period to make it 2-1.

But Lessard made it a two-goal game again after Tim Stapleton stole the puck at center ice and fed it to Brian Schwabe. He brought it down the left side before sending it across the ice to Lessard, who beat Berkhoel with 4:25 left in the second period.

Then Denver came back.

Brett Skinner took a pass off a faceoff and slid over to his right before wristing the puck toward the net. It hit Gauthier’s stick on the way into the goal.

Just 34 seconds later, Fulgham outraced Schwabe to a loose puck that was rolling slowly toward the Duluth goal. He swatted it over to Caldwell, who was all alone in front of the net and beat Reichmuth to tie the game with 16:56 left in the third.
