The Saints designated Styles (calf) to return from injured reserve Wednesday, Aaron Wilson of KPRC 2 Houston reports.
Styles was a full participant in Wednesday's practice, which were his first reps since tweaking his calf in a preseason game against the Rams in late April. The rookie fifth-rounder will likely need multiple full practices before being activated from IR, but he could make his NFL regular-season debut as soon as Sunday against the Vikings.
