Viking running back Adrian Peterson was back in at practice in a limited capacity Thursday with a calf injury.  He's expected to play and could have a big day against Kansas City Sunday.  Ryan Mathews ran for 92 yards and 2 touchdowns against the Chiefs last week.  Peterson is 6th in the NFL in rushing yards through 3 games this season.

Linebacker E.J. Henderson (knee) was also limited in practice Thursday after missing practice Wednesday.  Tight End Jim Kleinsasser (elbow) and safety Tyrell Johnson (hip) were also limited in practice Thursday.  The Vikings are 0-3 and will play at 0-3 Kansas City at noon Sunday, pregame on WJON at 11am.
