Jets and Dolphins released Friday injury reports ahead of Monday Night Football. Jets have multiple defensive absences: Jarvis Brownlee Jr. and Jermaine Johnson II sit out with ankle injuries, Kene Nwangwu is limited with a hamstring, and Tony Adams is limited with a hip issue, while Justin Fields is listed as concussion but is listed as fully participating. Josh Reynolds is dealing with a hamstring, and Jay Tufele is noted with an illness. Dolphins list Duck Strom and Jason Marshall Jr. as non-participants, Jaylen Waddle is limited by a shoulder, and Darren Waller and Ifeatu Melifonwu are managing injuries.

These updates shape Week 4 lineup decisions for MNF: Jets’ depth at cornerback and pass rush could be tested, while Dolphins' receiving corps face uncertainty with Waddle limited. Fantasy and DFS discussions center on injury-driven depth charts, replacement targets, and which players step up in high-leverage games.

Miami's secondary opens the season with questions, rotating safeties opposite Minkah Fitzpatrick as free-agent signees push for time. Davis is listed first but health and flux keep the depth chart unsettled, while Melifonwu recovers and earns snaps. On the outside, Storm Duck is expected to start, with Rasul Douglas’ signing adding immediate competition. Rookie Jason Marshall Jr. shows nickel potential, while multiple safeties can swap roles for versatility and misdirection in coverage.

Expect the Dolphins to lean on varied looks and interchangeability to slow Indianapolis. Mixing Fitzpatrick, Melifonwu, and Davis in different alignments alongside Duck and Marshall Jr. should create matchup advantages, aided by a pass rush that helps coverage time. The opener could hinge on how quickly the unit communicates and finishes plays rather than who officially starts.

Rasul Douglas joined Miami’s revamped secondary as Week 1 looms, with Minkah Fitzpatrick back in the fold and a mix of new safeties contending for roles. Two practices in, Douglas relies on a long-standing Jersey connection with Fitzpatrick to accelerate the fit in Mike McDaniel’s defense, but the group remains a work in progress after Kohou’s season setback and training-camp time lost by Melifonwu and Davis.

Week 1 against Indianapolis tests the regression-to-mean of a unit still learning each other. Douglas’ acclimation and the overall health of the safety room will shape early snaps and fantasy upside for the Dolphins’ back-end playmakers, while the division’s quarterback talent—like Josh Allen—keeps the pressure high on the unit.

Two hours of practice in Detroit left the Dolphins with a harsh but early August verdict: the joint session was "lopsided" and depicted as a rough day for Miami. Amon-Ra St. Brown torched Miami’s defense in 1-on-1s and 11-on-11s, signaling Lions' ceiling when everything is clicking, while Jared Goff looked sharp with no turnover, per the Herald live blog.

For Miami, Tua Tagovailoa and Zach Wilson faced pressure, Tyreek Hill flashed, and De'Von Achane showed a path to impact, but questions about the Dolphins' protection and playmaking linger. The piece stresses that training-camp outcomes don’t count, and the real test comes Week 1. Tapes will be reviewed for teaching and motivation, and the Dolphins still have time to adjust before the season begins.
