On a busy day for goaltenders on the NHL waiver wire, the Carolina Hurricanes put Scott Darling on waivers and the Arizona Coyotes claimed Calvin Pickard from the Philadelphia Flyers. Darling, who played two seasons (2008-2010) at the University of Maine, went on waivers Thursday with two years left on his contract beyond this season at a salary-cap hit of $4.15 million. The 6-foot-6, 232-pounder became Carolina’s third goaltender behind Petr Mrazek and Curtis McIlhenney, who the Hurricanes claimed from the Maple Leafs before the season began. Former Carolina general manager Ron Francis traded a third-round pick to Chicago for Darling in 2017 and signed him to a $16.6 million, four-year contract.
