Colorado got the 31st and 37th picks in this week's draft and defenceman Gianni Fairbrother from Montreal.
The move clears potential salary cap space to try to keep pending free agent centre J.T. Compher, after the Avalanche acquired Ryan Johansen from Nashville over the weekend.
Newhook tallied 66 points (27, 39) in 159 games for the Avalanche.
He was selected by Colorado as the 16th overall pick in the 2019 draft.
Newhook is expected as a restricted free agent to get a raise from the US$925,000 he made last season. The Boston College product had four points in 12 games on Colorado’s 2022 Stanley Cup run.
Fairbrother was the 77th overall pick by Montreal in the 2019 draft and has spent the last two season with the Laval Rockets.
He had eight points in 28 games for the AHL team but suffered a season-ending injury in a game against the Belleville Senators on Oct. 9, 2022.
Fairbrother is under contract through next season at an NHL salary of $860,000 and $80,000 in the American Hockey League.
