Here come the rookies

No. 1 pick Adrian Peterson will go through his first workout in a Vikings uniform today as he and the rest of the team's draft class open a three-day rookie minicamp.

In addition to their eight draft choices, the Vikings will have at least 15 undrafted free agents on hand and give tryouts to a number of other prospects, including a pair of former Gophers: offensive tackle Joe Ainslie and defensive back Trumaine Banks.

Today's session is the only one open to the media and all workouts are closed to the public.
