Ritchie was assigned to his junior team (OHL Peterborough) Monday, Helene Elliott of the Los Angeles Times reports. Ritchie, the Ducks' first-round pick in this past June's draft, faced long odds of making the Opening Night roster as an 18-year-old. That being said, he remains a highly interesting prospect due to his scoring prowess and willingness to hit, and could make noise for a potential call-up if injuries test the Ducks' depth on the wing.
