The Lions have released defensive end Robert Ayers just one day after signing the free agent, the team announced Tuesday.
Detroit signed Ayers on Monday, announcing his addition to the roster with the decision to waive cornerback Josh Okonye.
Ayers, a 10-year NFL veteran, spent the last two seasons with the Tampa Bay Buccaneers, totaling 31 tackles, two sacks and two forced fumbles in 2017.
A former first-round pick in the 2009 NFL Draft with the Denver Broncos, Ayers spent his first five seasons in Denver before playing two seasons with the New York Giants from 2014-15 and then the Bucs.
