There is no set plan yet, but the 40-year-old quarterback says he feels ready to return after undergoing thumb surgery in September.
Brees noted he needs to get through practices feeling himself this week, so his Wednesday optimism could wane if his surgically repaired thumb doesn't respond as he hopes.
So far so good for Brees, who was limited in the Saints' first practice of the week Wednesday. He said he felt good throwing and noted that taking a snap was easier than he anticipated.
Coach Sean Payton told Cardinals reporters in a conference call that he could wait until Sunday to make his decision on whether Brees can go.
The initial timeframe after Brees injured his thumb in Week 2 and underwent surgery was a four-to-six-week recovery. Sunday represents the five-week mark.
