With no N.H.L. players available for the 2018 Winter Olympics in Pyeongchang, South Korea, the United States men’s hockey team unveiled on Monday includes four college players, three from the American Hockey League, 15 playing in European leagues and 38-year-old Brian Gionta, who has not played for any pro team this season.

Gionta will be the captain of the American team, as he was for the Buffalo Sabres and the Montreal Canadiens over his 15 N.H.L. seasons. But he is the only player on the United States roster that has played in the Olympics before, participating in the 2006 Games, in which the Americans lost in the quarterfinals.

“I loved the N.H.L. players, but there’s something fresh about the format this time,” said U.S. Coach Tony Granato, an American Olympian himself in 1988 in Calgary. “We’re going to take advantage of that. We have to see how good we are.”

The four college players selected — Denver’s Troy Terry, Boston University’s Jordan Greenway, St. Cloud State’s Will Borgen and Harvard’s Ryan Donato — have won medals for the United States at the world junior championships over the past two years.
