New long snapper Aaron Brewer (46) takes part in his first practice with the Cardinals Wendesday.

The Cardinals have updated their special teams units.

Replacing Kam Canaday at long snapper will be veteran Aaron Brewer, who had played for Denver the last four years. Brewer had been cut by the Bears at the end of the preseason. The team also added veteran punter Ryan Quigley to replace the injured Drew Butler.

Originally, coach Bruce Arians said Butler would continue to hold in games, but noting the walking boot

Butler is now wearing, Arians said Quigley will likely hold in games. Butler remains on the roster although that could change with another injury, Arians said.

Quiqley has spent time with the Bears, Jets, Eagles, Jaguars and Buccaneers, averaging 45.1 yards a punt.

Arians said kicker Chandler Catanzaro was "100 percent, with a pretty good breeze" while Quigley held for him in practice, receiving snaps from Brewer.

As for Brewer, Arians called him "very consistent."

"He's got a lot of tape, he's very consistent in the league," Arians said.

A knee injury has also taken out inside linebacker Alani Fua, who heads to injured reserve. The Cardinals replaced him on the roster by signing Joplo Bartu, who has 4½ sacks in three NFL seasons with the Falcons and the Jaguars.

The Cardinals released Canaday Tuesday after the rookie had a couple of erratic snaps in three games, including one Sunday that resulted in a 53-yard touchdown for the Bills.

"It's all about nerves," Arians said. "Nerves have to be controlled.

"I want Kam back because the kid has a lot of talent. Once he gets those nerves under control, it's just like those young guys on (the PGA) tour putting."
