North Dakota gave up a season-high 46 shots on goal and were outshot by the Bulldogs in every period except the 5-minute overtime session, when UND had a 2-0 edge.
UND had leads of 2-1 and 4-3 but gave up the tying goal at 14:08 of the third period to Bulldog senior defenseman Drew Olson with his first of the season and just his third in 118 career games.
"It's definitely a rivalry that has heated up over the past couple of years,'' said UND senior left wing Danny Kristo (Eden Prairie, Minn.), who scored two goals to lead UND's offense. "It was getting pretty chippy there in the third (period), so expect a good hard-fought game tomorrow.''
Freshman center Rocco Grimaldi (Rossmoor, Calif.) had staked UND to the 4-3 lead at 12:47 of the third period with his fourth goal of the season.
He beat Duluth goalie Aaron Crandall high to the short side from a sharp angle.
"I just kind of put it on net,'' Grimaldi said of his goal. "I think it just went the goalie and went in. I just tried to drive it to the net and shoot for something. It hit his glove or shoulder and kind of went up, so I was happy that went in.''
UND coach Dave Hakstol cited sporadic play defensively and aggressive play by the Bulldogs leading to the 46-33 advantage in shots on net for Duluth.
"That's too many (shots) to give up in our own building,'' said Hakstol, who saw his team give up 37 shots last Saturday in a 5-2 loss at St. Cloud State. "They worked awful hard for them. They played hard through 60 minutes. So did we.''
North Dakota's play, though, was not as consistent as Hakstol would have liked. "We were a little too sporadic at times,'' Hakstol said. "That soaked away some of our momentum at different times. But it was really hard-fought, back-and-forth hockey game.''
While the game goes down as a tie, it goes down as a loss for North Dakota as far as player personnel goes.
Sophomore wing Michael Parks (St. Louis, Mo.), making his season debut after recovering from injury, left the game in the first period and didn't return. Hakstol had no additional information on the status of Parks immediately after the game.
UND senior defenseman Andrew MacWilliam (Calgary, Alberta) answered an early Duluth goal by Mike Seidel on a giveaway with his third career goal at 13:39 of the opening period. His wrister from the right point came after extremely heavy pressure by UND in the Bulldog zone.
Kristo scored his first of two goals on a rebound at 1:40 of the second period, but freshman Austin Farley scored on a power play at 6:57 and again with sides even at 10:03 to put the Bulldogs on top at 3-2.
Kristo tied it 36 seconds after Farley's second goal, taking a drop pass from freshman Drake Caggiula (Pickering, Ontario) and ripping a wrist shot high to the far top corner.
That set up the third period when Duluth outshot North Dakota 17-7 but needed Olson's goal to match Grimaldi's tally to force overtime.
"I've said it all along that Duluth is a good hockey team,'' Hakstol said. "They played that way tonight.''
Hakstol said he liked the fight North Dakota had. "But we need to do a better job,'' he said. "Seven minutes left in the game, we built a one-goal lead. I thought we gave that up a little too easily.''
Junior Clarke Saunders (Brockville, Ontario) finished with 42 saves for North Dakota compared to 29 for Crandall.
