Harrison told reporters after the season that he wasn’t sure if he would return next year.
“I got to talk it over with my family, try to seek some different options. But if I do walk away, I’m not ashamed, I don’t feel bad. Because I gave it everything I had, even when it wasn’t good enough,” Harrison said.
“I’ve given everything I have to every team I’ve played for. I don’t feel bad if (retirement is) the decision,” Harrison added. “I got a lot of thinking to do this offseason, I’m going to seek some different options. … But if I can’t be that guy I want to be, then I got to hang it up.”
Harrison, 31, originally signed on with the Jets as an undrafted free agent out of William Penn back in 2012. He spent four years with the Jets before departing in free agency for a five-year, $46.25 million contract with the Giants.
The Giants later traded Harrison to the Lions. He was entering the fourth year of his five-year, $46.25 million deal when he agreed to a one-year, $11 million extension this past August.
According to OverTheCap.com, releasing Harrison will free up $6,718,750 of available cap space while creating $5 million in dead money.
In 2019, Harrison appeared in 15 games for the Lions and recorded 48 tackles, two sacks and three pass defenses.
