Veteran cornerback Antoine Winfield was not in attendance Tuesday as the Vikings began another round of practices that are part of Organized Team Activities, according to people with knowledge of the situation. Winfield's absence came after he missed the team's mandatory three-day minicamp this past weekend because he was attending the funeral for a mother of a close friend, according to coach Brad Childress. Winfield's decision to stay away from Winter Park also could be tied into the fact he is entering the last season of his contract and negotiations on an extension broke down early last month.
