Storm Duck exited Sunday’s opener with an ankle injury and is questionable to return, testing Miami’s revamped secondary early. Jack Jones started opposite him, while Rasul Douglas—signed recently—stepped in as the veteran fill-in. Miami’s defensive plans now hinge on Douglas and a young, growing group in 2025, shaping Week 1 fantasy outcomes for Dolphins DBs and Colts pass catchers.

Tyler Warren’s involvement for Indianapolis offered a glimmer of the Colts’ passing potential, and the evolving injury stories will be watched closely for fantasy lineups and streaming defenses as the week unfolds. The Dolphins’ depth chart change adds volatility, but also upside for opportunistic lineups.
