Avonte Maddox goes to injured reserve as Lions add Bishop Fitzgerald to the secondary

The Detroit Lions placed defensive back Avonte Maddox on injured reserve Tuesday and signed safety Bishop Fitzgerald from the Pittsburgh Steelers' practice squad to the active roster. The official transaction log also shows Detroit released linebacker Joe Bachie. The moves create a defined secondary vacancy and give RSO managers a current depth-chart development to track before Detroit's next game.

Detroit did not publish an injury diagnosis or return estimate in the transaction entry. The IR designation guarantees at least four missed games under the league's standard regular-season procedure, but Maddox's position label covers a defensive-back role rather than one fixed assignment. Managers should wait for the Lions' practice report and defensive personnel packages before attaching a specific starter or coverage matchup to the move.

Fitzgerald's promotion is the actionable part of the transaction. He was signed from Pittsburgh's practice squad, which gives Detroit an available body immediately but does not establish a full-time role. The Lions also signed defensive back Jalen Mills to the practice squad on Monday, so the club is adding options rather than naming one replacement in the public transaction log. That competition matters for IDP leagues and for opponents whose target distribution could shift if Detroit changes its coverage structure.

The roster move comes against a crowded Detroit injury context. The same official page lists Brian Branch and Kerby Joseph on reserve lists from the preseason, while the Lions have continued adding defensive backs around those absences. That makes snap counts and formation usage more informative than Fitzgerald's transaction alone. If Detroit uses him in a defined safety package, his IDP value can grow quickly; if the club rotates several defensive backs, the short-term floor stays low.

Maddox should be held in dynasty formats until the team provides a diagnosis and return path. Fitzgerald is a speculative waiver add only in deep IDP leagues that reward defensive-back volume, and Mills is worth monitoring after the practice-squad signing. The next reliable update is Detroit's injury report, followed by the game-day inactive list and first-week snap distribution.

This is a roster adjustment with fantasy consequences because it changes who may be available, not because a new starter has already been announced. RSO managers should preserve that distinction while the Lions fill out the secondary.
