Winovich (hamstring) returned to practice Wednesday, Anthony Poisal of the Browns' official site reports.
Winovich, who played in the first preseason game, apparently sustained the injury then and has been sidelined since. He's one of five defensive ends on the initial 53-man roster announced Tuesday. That means he could have a substantial role in the rotation if healthy, or it's a spot that can be jettisoned if a player at another position is deemed a better roster fit.
