The NFL on Saturday confirmed that Cowboys quarterbacks coach Wade Wilson admitted to NFL officials that he bought and used performance-enhancing substances while an assistant with the Bears. Wilson, who has been suspended for five games by the league and fined $100,000, told ESPN.com's Matt Mosley that he used a substance, which he did not specify, to treat his diabetes. He said he did not pass the drugs along to anyone else and that he had "no regrets on trying to improve my quality of life." Wilson acknowledged he acted without "proper medical supervision."
