Winfield's right foot injury prompted the Vikings to reduce his role in the regular-season finale against the New York Giants. He was replaced in the lineup by Benny Sapp and took the slot position in the nickel defense package for that game.
Coach Brad Childress said Wednesday that Winfield "seems to be pretty comfortable," three months after he first got hurt.
Winfield missed 6½ games, returning for the last four. He aggravated the injury in his first game back and played at less than full speed.
Childress declined to elaborate on which matchups would dictate his positioning against the Cowboys.
