Johnson was not much of a participant in the Cowboys’ organized team activities as his school’s schedule prevented him, by NFL rules, from practicing until the final day. He then missed most of training camp with a hamstring injury.
He tweaked the hamstring after only three preseason snaps against the Rams on Aug. 25 and sat out Wednesday’s exhibition finale against the Dolphins.
Johnson was one of five safeties the Cowboys kept, joining starters Gerald Sensabaugh and Barry Church and backups Mana Silva and Danny McCray.
