New England Patriots safety Jabrill Peppers said his legal team is cooperating with the NFL's ongoing investigation, but isn't sure when he might be back after being removed from the commissioner exempt list and becoming eligible to participate in practice and play in the team's games.

Peppers was removed from the commissioner’s exempt list on Monday and returned to practice Tuesday for the first time since he pleaded not guilty on assault, strangulation and drug charges in October. His first practice back was a walk-through in the Patriots’ practice bubble.
