McCoy (groin) was placed on injured reserve Wednesday, Ross Jackson of WWL Louisiana reports.
McCoy's move to IR was imminent, as the 27-year-old sustained a groin injury during the Saints' Week 3 loss to the Eagles that requires surgery and is expected to sideline him for the next 6-to-8 weeks. Lucas Patrick will likely assume the Saints' first-team center duties while McCoy recovers from surgery.
