Helleson had a goal, four SOG, and two PIMs through three games with Anaheim but has been reassigned to San Diego (AHL) for the remainder of their season. The 22-year-old returns to San Deigo (AHL), where he had five goals, 13 assists, 50 PIMs and a -18 plus/minus through 63 games earlier this season.

Helleson was recalled from San Diego (AHL) after putting up a goal and two points along with 16 PIMs and a -5 plus/minus across 13 games. The 21-year-old is a 2nd round pick (47th overall) from 2019 and has yet to appear in an NHL game.

Helleson was acquired from the Avalanche in the Josh Manson trade on Monday and signed with the Ducks on Tuesday. Helleson, who has 25 points (4G / 21A) in 32 games at Boston College this season, is expected to play in the AHL after the college season is over.

Helleson was a fourth-round pick in 2019 and is coming off of a great season at Boston College, scoring four goals with 21 assists (25 points) in 32 games.
