Iorio (lower body) landed on injured reserve Monday, according to PuckPedia.
Per Mollie Walker of the New York Post, Iorio skated Monday in a non-contact jersey, so his injury doesn't appear to be overly serious. The Rangers had to either waive Iorio or place him on IR on Monday in order to be compliant with the 23-man roster limit, but it's currently unclear how long Iorio will be sidelined for.
