Zenner (concussion) is active for Sunday's game against the Giants in New York, Tim Twentyman of the Lions' official site reports.
Although he'll avoid the inactive list one week removed from sustaining a concussion, Zenner's workload could be capped in order to avoid a setback. No matter the approach employed by the Lions, Dwayne Washington is poised to handle the bulk of the work out of the backfield with Theo Riddick (wrist) out of commission.
