GLENDALE, Ariz. -- This could be the week that the Arizona Cardinals activate inside linebacker Deone Bucannon off the physical unable to perform list, but if it is, he won't jump right back into the fray.

Cardinals coach Bruce Arians said if Bucannon is taken off the PUP list this week, it'll be so he can start participating in walk-throughs. Arians also added that if he's activated this week, Bucannon could begin practicing as soon as next week.

Bucannon had surgery to repair an ankle injury that landed him on injured reserve for the final three weeks of the season. The initial timeline for his return was set at Week 1, but the Cardinals aren't in dire need for him to return with rookie Haason Reddick showing signs of improvement weekly. He's currently penciled in as the starter at Detroit on Sept. 10 alongside Karlos Dansby, who's missed time during the preseason with a leg issues.

"We haven't been counting on Deone," Arians said. "That's going to be a blessing. We're counting on Karlos (Dansby) and I think he'll be fine. Haason's getting better. Josh Bynes has been a great find. Scooby (Wright), when he's played his own position and not a new position was OK and played well on special teams.

"I don't look at it as a gloom or doom thing because I think Karlos will be fine."
