The Bears released Trevathan (knee) on Wednesday.
Trevathan appeared in just five games for Chicago, logging 19 tackles (eight solo) before finishing the season on injured reserve due to a knee injury. Since Chicago isn't waiving him in an injury settlement, Trevathan is presumably healthy again heading into the 2022 campaign. After spending the last six seasons with the Bears, the 31-year-old will now attempt to find a new team.
