Jack Campbell: Everything you need to know

The Lions declined Campbell's fifth-year option Tuesday, Nolan Bianchi of The Detroit News reports. Campbell is coming off the most productive season of his career, logging 176 tackles (89 solo), including 5.0 sacks, but that seemingly wasn't enough to convince Detroit to exercise his option. The 25-year-old will now play out the final year of his rookie deal during the 2026 campaign and look to earn a contract extension.

Campbell recorded 176 total tackles (89 solo), including 5.0 sacks, while also adding four passes defensed, three forced fumbles and two fumble recoveries over 17 contests during the regular season. Campbell found a way to take another step up in his third campaign in Detroit, setting new career high totals in tackles, sacks, forced fumbles and fumble recoveries. The linebacker finished second in the NFL in total tackles only behind Dolphins linebacker Jordyn Brooks (183). Campbell will be entering the final season of his rookie contract in 2026.

Campbell posted six tackles (two solo) during the Lions' 23-10 loss to the Lions on Thursday. Campbell played every single defensive snap and finished tied with Aidan Hutchinson as the Lions' second-leading tacklers behind Daniel Thomas (seven). Campbell's six stops were a season low and broke a three-game streak of 10-plus tackles, but it's still been a productive campaign for the third-year pro out of Iowa. He has accumulated 165 combined tackles through 16 regular-season games, which is second most in the NFL behind Jordyn Brooks (169).
