No team made a claim on Darling, who carries a $4.15 million cap hit, and he was reassigned to the Hurricanes' AHL affiliate in Charlotte.
Darling was 2-4-1 with a 3.14 goals-against average and an .892 save percentage this season. In his last game with Carolina, he allowed four goals on 19 shots in Saturday's loss to the New York Islanders.
The Hurricanes had acquired Darling in a 2017 trade with the Chicago Blackhawks and signed him to a four-year deal worth $16.6 million. The 29-year-old has gone 15-25-8 with a 3.17 GAA and .889 save percentage in 50 games with the Hurricanes.
In addition, the Hurricanes waived Valentin Zykov. The 23-year-old forward had one assist in 13 games this season.
