PHOENIX (AP) — Arizona Cardinals quarterback Carson Palmer is retiring after 15 NFL seasons.
Palmer, who turned 38 last week, made the announcement in an open letter released Tuesday by the Cardinals. Palmer missed the last nine games of what would be his final season with a broken left arm.
He called his long professional career “the most incredible experience of my life.”
The statement came one day after Cardinals coach Bruce Arians announced his retirement. Arians and Palmer spent the last five seasons together.
