The Patriots also designated DB Cody Davis to return from injured reserve and placed TE Jake Burt on the practice squad injured list.
This opens a three-week window of time for the Patriots to activate Davis from injured reserve and add him to their 53-man roster.
Copeland, 29, originally signed on with the Ravens as an undrafted free agent out of Pennsylvania back in 2013. He lasted just a few months with the team before he was waived and later caught on with the Titans during his rookie season.
After a year in Tennessee, Copeland signed a one-year contract with the Lions and returned to Detroit on a one-year, $615,000 exclusive rights contract the following year. The Jets signed Copeland to a contract in 2018 and he returned to New York last year on a one-year deal worth up to $3 million.
The Patriots signed Copeland to a one-year contract this past March.
In 2020, Copeland has appeared in six games for the Patriots and recorded 12 tackles and no sacks.
