Arizona Cardinals kicker Matt Prater is questionable for the upcoming game against the San Francisco 49ers due to a left knee injury. After only participating in a limited practice on Friday, his status raises concerns for fantasy football managers. With the Cardinals' low implied total of 21.25 points, Prater is not recommended for fantasy lineups this week.

• Matt Prater's injury status makes him a risky play for Week 5.
• Arizona's low implied total further diminishes Prater's fantasy value.
