What happened: Seattle acquires the Notre Dame product after Indianapolis drew strong trade interest in both Nelson and DeForest Buckner, per Jordan Schultz and Adam Schefter. Nelson entered the midseason market on an expiring contract after extension talks with Indianapolis remained stagnant before Week 1.

Why it matters: Moving a foundational offensive lineman marks the first major roster shakeup for Indianapolis following a recent general-manager change. The front office also placed running back Jonathan Taylor on transaction watch this week.

What to watch: Teams have until the Nov. 10 NFL trade deadline to finalize deals as Indianapolis weighs further moves involving Buckner and Taylor.
