Harris (hamstring) was designated to return from injured reserve Wednesday, per the NFL's transaction log.
Harris sustained a hamstring injury in the Saints' Week 5 loss to the Chiefs that has sidelined him since. However, the 28-year-old's practice window opened Wednesday, suggesting that he's nearing a return to the field. Harris now has a chance to suit up for Sunday's matchup against the Falcons, but he must be activated to the Saints' active roster in order play.
