Lions general manager Martin Mayhew has confirmed that linebacker Julian Peterson will not return to the team next season. "We had a meeting on Monday, a great meeting, and I thanked him for his two years of service," Mayhew said. "Anytime you make 31 straight starts for a team, you have given a lot of blood, sweat and tears to make that happen. I thanked him and told him we weren't going to bring him back."
