Hufanga (ankle) doesn't have an injury designation for Sunday's matchup with Arizona, Nick Wagoner of ESPN.com reports.
Hufanga missed Week 4 versus New England due to an ankle issue, but he'll be able to return one week later. The safety has played in just one game so far this season, notching seven tackles (four solo) in Week 3 against the Rams. Hufanga's return means Malik Mustapha likely will return to a rotational role after playing all 62 defensive snaps Week 4.
