MINNEAPOLIS (AP) - The Minnesota Vikings apparently will hold optional practices this week without Adrian Peterson.

A person with knowledge of the situation tells reporters that the running back has informed Vikings coach Mike Zimmer that he will not be attending. Peterson has been unhappy with the Vikings for a perceived lack of support from within the organization while he addressed child abuse charges last season.

The Vikings have said they have no plans to trade Peterson, who could lose out on a $250,000 workout bonus by skipping the practices this week. He is not required to attend any team functions until a mandatory minicamp next month.
