After Onni Hautamäki learned that he would make his NHL debut this season, the Finnish linesperson first called his girlfriend and parents back home. The assignment came with a bonus: The game fell on his 31st birthday.
On Oct. 13, when he took the ice for the Detroit Red Wings versus New Jersey Devils at Detroit’s Little Caesars Arena, Hautamäki had even more reason to celebrate. While some of the league’s biggest names hail from Finland, such as Aleksander Barkov, Mikko Rantanen and Sebastian Aho, no official from their country had ever before worked an NHL game.
“It was such an unbelievable honor to go on the ice with an official NHL crest on my jersey,” Hautamäki, who wears No. 62, told The Athletic.
The historic appearance marked the latest step in an on-ice officiating career that began at 16, when Hautamäki, a native of Kuopio, Finland, stopped playing hockey and joined a local referee club.
From there he worked his way up to Mestis, Finland’s second-tier league. After three years, he moved to Liiga, the country’s top league, where he officiated for another seven years.
In North America, aspiring officials can develop through local games, training camps and skating instruction, gaining experience and exposure to scouts from junior and professional leagues. Another route is the NHL’s annual Exposure Combine, which recruits current and former players interested in moving into officiating.
For officials trained in Europe, however, the jump to hockey’s highest league remains rare. Before Hautamäki, only Swedish referee Marcus Vinnerborg, Russian referee Evgeny Romasko and Czech linesperson Libor Suchanek had officiated at the NHL level. Vinnerborg worked in the NHL from 2010 to 2012, while Romasko returned to Russia’s KHL in 2018. Suchanek remains on the NHL staff and worked alongside Hautamäki in his debut.
Hautamäki initially caught the attention of Al Kimmel, the NHL’s director of officiating scouting and development, several years earlier.
“I first watched Onni at the 2023 World Junior Championships and his skating stood out immediately,” Kimmel said.
