Baltimore's leading rusher from its season-opening demolition of the Bills won't return to the field for some time.
NFL Network Insider Ian Rapoport reported earlier Wednesday that Dixon was expected to miss several weeks. Dixon can be designated to return from IR after Week 8.
Dixon's injury is an unfortunate setback for a promising player with terrible injury luck. The running back has missed 20 of a potential 33 regular-season games due to knee injuries or suspension. He sat out the entirety of the 2017 campaign.
