KANSAS CITY, Mo. — KANSAS CITY, Mo. (AP) - Chiefs quarterback EJ Manuel, who was signed this off season to compete for a backup job, has decided to retire after four seasons with Buffalo and one season with Oakland.    

Manuel was the 16th overall pick of the Bills in the 2013 draft, going 6-11 while struggling to live up to expectations. He'd been Derek Carr's backup the past two seasons with the Raiders.     

His retirement was part of a series of roster moves the Chiefs made Monday.
