Two players who failed to take a snap for the Cowboys last season have been active on the practice field in recent days.
Travis Frederick and Jason Witten didn't play in 2018 for vastly different reasons. Frederick was leveled by Guillain-Barre syndrome, an autoimmune disease, in training camp. Witten retired a little more than a year ago for a spot in the Monday Night Football booth.
Both intend to resume their careers and have taken part in the team's offseason program. Phase Two began last week when the players took the field for drills, teaching sessions and individual instruction with coaches.
