Injury Index
A structured, data-first view of NFL injuries and how they correlate with on-field performance, win probability, and season outcomes.
What the Injury Index Tracks
The Injury Index consolidates team and player injury information into a single, comparable framework. It is designed to help you understand how availability and injury severity connect to game-level and season-level results.
- Weekly injury status by player (out, doubtful, questionable, full)
- Injury type, body area, and reported timeline
- Snap share and role change before and after injury
- Team-level injury burden by unit (offense, defense, special teams)
- Correlation with point differential, EPA, and win probability
Status: In Development
This page is a placeholder for the full Injury Index experience. Data feeds, definitions, and visualizations are being tested and validated to ensure consistency with official league reporting and existing site metrics.
Once live, this section will support interactive queries, cross-filtering by team and position, and side-by-side comparisons against game outcomes.
Planned Metrics and Views
Team-Level Index
Aggregate indicators showing how injury load evolves across the season by team, with breakdowns by unit and position group. Designed to align with existing team efficiency and schedule-strength metrics.
Player Availability Profile
Player-level timelines mapping practice status, game status, and snap counts, enabling direct comparison between health reports and actual usage.
Outcome Impact View
Game-level summaries linking pregame injury reports to point spread results, win probability shifts, and efficiency metrics such as EPA per play.
Methodology Snapshot
The Injury Index framework is grounded in official NFL injury reports, play-by-play data, and publicly available participation logs. The goal is to provide a consistent, reproducible way to connect reported injury information with on-field outcomes.
- Data sources: team injury reports, official gamebooks, participation reports, and play-by-play feeds.
- Standardization: consistent fields for status, body area, side, and practice participation.
- Alignment: week-by-week integration with existing site metrics for efficiency, game state, and win probability.
- Validation: back-testing across multiple seasons to confirm stability and interpretability of the index values.
