Cardinals dollar linebacker Deone Bucannon stands under a goalpost watching a recent training camp practice. Bucannon was taken off the PUP list Tuesday.

Deone Bucannon isn't practicing yet, but the Cardinals officially activated the linebacker from the physically-unable-to-perform list Tuesday.

Bucannon, recovering from ankle surgery, came off PUP so he can at least begin taking part in morning walkthroughs. Coach Bruce Arians said the hope is Bucannon can begin to start practicing some next week prior to the final preseason game.

"It's great just to be a part of it," Arians said. "To be able to walk through, get his eyes going, get his keys. Watching film and standing behind, you don't get that, that view of where he needs to be."

All along, Arians had said he hoped to get Bucannon at least a week of practice before the regular-season opener Sept. 10 in Detroit. His availability for that first game remains in doubt.

"We haven't been counting on Deone," Arians said. "That's going to be a blessing (if he plays)."

Bucannon first hurt the ankle early last season, playing on it much of the year before heading to injured reserve with three games left in the season. The hope had been the ankle would heal without surgery, but he and the team realized that wouldn't be the case by the end of Phase Two workouts. Before OTAs started in May, Bucannon underwent surgery.

"I want to start the (regular) season," Bucannon said prior to training camp. "I'm not here to rush anything and I'm not going to put a timetable on it, but at the same time, I want to get out there as quickly as I possibly can. But get out there at 100 percent so I can do the best for the team and not be a liability."

In Bucannon's absence, rookie Haason Reddick has been with the first-string at his inside linebacker role, next to veteran Karlos Dansby.

"(Bucannon) is nowhere near ready," Arians said. "But it's a good beginning."
