Kennard (undisclosed) was placed on the reserve/COVID-19 list Wednesday, Darren Urban of the Cardinals' official site reports.
Kennard will be fighting an uphill battle to gain clearance in time to suit up Sunday against the Cowboys for a pivotal game with playoff positioning on the line. The 30-year-old linebacker has been a solid depth piece for the Cardinals this season, totaling 20 tackles in 14 games.
