Campbell was inactive for three of 17 games for the Ravens last year, but it doesn't look like he was ever placed on injured reserve.
Not surprising for a mid-30s DE, his snap counts have dropped a good bit in recent years. He was consistently over 800 snaps/season with Arizona and Jacksonville, then dropped to 412 snaps (12 games) his first season with the Ravens in 2020.
In 2021, the Ravens leaned on Campbell for 612 snaps (15 games) and his production fell off a cliff. Last season, they used Campbell more situationally and limited his rushing-downs snaps. He bounced back a bit on a per-play basis in 2022 -- 36 combined tackles with 5.5 sacks in 550 snaps (compared to 29 combined tackles and 1.5 sacks in 612 snaps the year prior).
