Vikings outside linebacker Erin Henderson missed practice because of a concussion that presumably was sustained in Sunday's loss at Indianapolis. He'll have to pass the NFL-mandated post-concussion tests before being allowed back onto the field.
Center John Sullivan (ankle) was limited in practice. Everyone else had full participation, according to today's injury report.
Defensive starters Chris Cook (biceps) and Brian Robison (elbow) were among six other players on the injury report that had full participation. The other four -- safety Andrew Sendejo, tight end Rhett Ellison, linebacker Marvin Mitchell and receiver Jarius Wright -- have ankle injuries.
