Bruce Arians hints at center Lyle Sendlein's retirement

TEMPE, Ariz. -- Unlike last year, center Lyle Sendlein might not be an option for the Arizona Cardinals to re-sign during training camp.

The 32-year-old Sendlein is likely retiring -- coach Bruce Arians hinted as much during the NFL owners meetings in Boca Raton, Florida, on Wednesday.

"As far as I know," Arians said. "I don't think he's announced it yet."

Without the possibility of bringing back Sendlein, who's an unrestricted free agent, for a training camp battle at center, A.Q. Shipley has been slotted as the first-team center, Arians said.

"He will right now," Arians added. "We'll start adding pieces and everybody's competing. Nobody on our team has a job."

Shipley was signed a day after Sendlein was cut last March and beat out Ted Larsen for the starting center job during organized team activities and held on to it through training camp. But Sendlein was instituted as the starter in Week 1.

Arians said it was a battle that came down to the end.

"That thing went right to the last minute with A.Q. last year," Arians said. "A.Q. played the whole Philadelphia game and we rushed for 240.

"There isn't that much of a drop off. They went back and forth. Lyle was the vet but I have all the confidence in A.Q. Shipley."
