July 16 (UPI) -- Veteran NFL defensive end Robert Ayers announced his retirement Tuesday after nine seasons.
"That's all folks, so thankful," Ayers wrote on Twitter. "[It] was a helluva run NFL but the time has come. On to the next chapter of life."
Ayers joined the New York Giants as a free agent in 2014 and recorded a career-high nine sacks with the team in 2015.
Ayers spent his final two seasons with the Buccaneers. He was released one day after signing a one-year contract with the Detroit Lions last August.
Ayers recorded 35 sacks and forced nine fumbles in his career.
