After 14 seasons in the NFL, quarterback Carson Palmer is calling it a career.
Palmer, who spent the past five seasons with the Arizona Cardinals, said he "just know[s]" its time for him to hang the up.
"For me that time is now. Why? Quite simply, I just know," Palmer said in a statement. "For 15 years I have been lucky enough to play quarterback in the NFL and it has been the most incredible experience of my life. There wasn't one second that I took it for granted or failed to appreciate what a tremendous privilege it is. ... And like most things in life, it feels like it all passed in the blink of an eye. In the end, it's not what happens on the football field that sticks with you. Those are details that I know fade with time. What I will never forget are the relationships."
Palmer was signed for next season at a base salary of $12.5 million. He was due to receive a $1.5 million roster bonus on April 1.
After wining the Heisman Trophy his senior year at USC, Palmer was drafted first overall in the 2003 draft by the Cincinnati Bengals.
Palmer, 38, led both the Bengals and Cardinals to resurgent eras during his career, leading both franchises to playoff appearances. He also spent two seasons with the Oakland Raiders.
