John Brown, who is still suffering recurring headaches from a July 31 concussion.
Although Brown returned to practice last week, he's not prepared to declare himself ready for Week 1.
"I'm just taking it one day at a time," Brown said Monday, via The Arizona Republic. "My focus right now is just being able to practice, just being able to get through a full practice."
Brown noted that this is his first career concussion, and he felt "fine" after Monday's practice. Coach Bruce Arians continues to take a cautious approach with the third-year wideout and Arians said he's been concerned the whole time. J.J. Nelson and Jaron Brown are next up on the depth chart should John Brown not be able to go.
