Boston: The Boston Bruins have signed Ryan Donato to a two-year, entry-level deal and say the US Olympic star could play for them right away.

Donato had 26 goals and 17 assists in 29 games this season at Harvard. He led the United States with five goals and six points at the Olympics as one of their youngest players.

The 21-year-old is eligible to be in Boston’s line-up Monday night against the Columbus Blue Jackets, a big boost to the Stanley Cup contenders down the stretch.

Donato was a second-round pick for Boston in 2014, and the team retained his rights while he played for his father, Ted Donato, a former Bruin who has been the coach at Harvard since 2004.
