Colorado claimed Reilly off waivers from Carolina on Sunday, per Elliotte Friedman of Sportsnet.
In eight NHL appearances this season, Reilly has contributed two assists, nine shots on net, six blocked shots and 15 hits. He could make his Colorado debut as early as Wednesday against Utah. With Cale Makar (lower body) out for about two weeks, Reilly will provide some much-needed defensive depth.
