The U.S. had heavily outplayed Slovenia through the first 40 minutes and led 2-0 entering the third.
Slovenia, ranked 15th by the International Ice Hockey Federation, got on the board in the third period when Blaz Gregorc threaded a wrist shot through a crowd in front of US goalkeeper Ryan Zapolski.
That has left teams to build their rosters from emerging local talent or from players in other professional leagues, largely from Europe. As Mursak's shot went past goaltender Ryan Zapolski, US players hung their heads on the bench before Slovenia players celebrated with their fans. While there won't be any household names playing in the tournament, outside of former NHLer Brian Gionta, when the Americans open play on Wednesday against Slovenia, the "replacements" are eager to show the world their talent.
In the second period Jordan Greenway, the first African American to play for the US men's Olympic hockey team, tapped in a puck that popped loose from a scrum in front of Kroselj. O'Neil also registered the secondary assist on the goal.
Zapolski got out of position after lunging to his left on a save.
In 3-on-3 overtime, after a scoring chance for the United States, Slovenia brought the puck down ice and, on a break-in, made sure it got on to the stick of their captain for the winning goal. But Ticar retrieved the puck and stubbornly repeated the task.

And Puel claimed both he and the Algeria worldwide will focus their efforts on the rest of the season without any issues. De Bruyne, meanwhile, has registered more assists than any other player in Europe's top five leagues since 2012.
In Wednesday's game, the USA got goals from Brian O'Neill and Boston University's Jordan Greenway. Only the Olympic Athletes from Russian Federation, which boasts KHL stars like Pavel Datsyuk and Ilya Kovalchuk, brings any sort of real star power to the event. "It's a good team, I'll give them credit".
If you missed the game, we're here for you.
After the 2012 lockout, preparing for a shot at a full season with the Wings, Mursak broke his collarbone. He was on the ice for Slovenia's first goal, but not the final two.
In the absence of the NHL, which chose not to send players to Pyeongchang, the USA men's national team is comprised of outcasts.
Wednesday's pool-play game will decide which part of the elimination bracket the United States and Canada land on.
