Rangers put Joonas Korpisalo on IR in early test of goaltending depth

The Rangers already have a goaltending issue to navigate in the first week of the season.Backup goalie Joonas Korpisalo is being placed on injured reserve with a lower-body injury, according to The Post’s Mollie Walker.Korpisalo, who participated in a brief practice Wednesday but didn’t in a lightly attended optional skate Thursday morning, is week-to-week, and the Blueshirts recalled Dylan Garand — who lost the competition to serve as the No.
