All three players will become unrestricted free agents.
Beaulieu, 26, was acquired by the Jets from the Buffalo Sabres at the trade deadline. In 18 regular season games, the defenceman had five assists. He was a healthy scratch for the team’s six playoff games against the St. Louis Blues.
Dano began the season with Winnipeg, was lost on waivers to the Colorado Avalanche in October, and reclaimed off waivers by the Jets in November. The 24-year-old forward failed to register a point in eight NHL games with the Avalanche, but had 12 goals and 30 points in 51 games with the AHL’s Manitoba Moose.
Morrow, 26, appeared in 41 games for the Jets last season, in which he scored one goal and seven points.
Meanwhile, the Jets did extend qualifying offers to young stars Patrik Laine and Kyle Connor, as well as the recently acquired Neal Pionk, Andrew Copp, Eric Comrie and Nelson Nogier.
The deadline to issue qualifying offers to potential restricted free agents is 5 p.m. ET on Tuesday.
