Styles sustained a calf injury during the Saints' 34-0 preseason loss to the Rams on Saturday, Matthew Paras of The New Orleans Times-Picayune reports.
Styles will undergo tests over the next couple of days to determine the severity of his calf injury, which could prevent the rookie fifth-rounder from playing in Friday's preseason finale against the Cowboys. He finished Saturday's game with six tackles (four solo) and one pass defense.
