What happened: Chris Johnson was fined after a Week 1 hip-drop tackle that falls under the league's suspension-tracking foul categories. Buffalo Bills and Green Bay Packers players were also listed under the same discipline bucket.

Why it matters: Placement in that category matters because repeat fouls can draw heavier league scrutiny as the season moves on. It also keeps player-safety enforcement in focus for teams trying to avoid avoidable discipline.

What to watch: Watch for whether Johnson or players from Buffalo and Green Bay appear again in the same discipline category as the season unfolds. Repeat entries would raise the stakes around league discipline.
