The Lions signed the cornerback to a two-year, $20-million deal last offseason but Trufant failed to stick in Detroit's secondary. He appeared in just six games and recorded one interception.
Trufant's departure will save the Lions $6.1 million in salary cap for 2021.
Trufant started his career with the Atlanta Falcons and has recorded 14 interceptions over his eight-year career. The 30-year-old cornerback has battled injuries as he's aged, appearing in only 15 games over the last two seasons.
