Domingue was designated for waivers by the Rangers on Tuesday, per PuckPedia.
Domingue was always going to be the third option in New York behind Igor Shesterkin and Jonathan Quick, so his potential demotion shouldn't come as a surprise. There could be some teams interested in submitting a claim for the veteran Domingue, especially clubs dealing with goaltending injuries like Anaheim, Pittsburgh and Chicago. If he clears, Domingue should report to AHL Hartford.
