Compared with the league
Z-scores: how many standard deviations a number sits from the average it is compared with. +1.0 is one standard deviation above it. Red means more than average, green fewer. Switch to totals for the counts behind the z-scores; the colors stay the z-scores.
* Statistically significant: a z-score of at least 1.96 either way (p < 0.05, two-sided). Each cell is tested on its own, so in a table of many cells about one in twenty would be marked by chance alone.

About this data
About the NBA data
Where the data comes from
Every injury on this site comes from what the leagues publish themselves; nothing is taken from stats sites or blogs.
- NBA and WNBA: the official injury report teams file before every game. The site uses the last report of each day of the regular season. The WNBA began publishing a league-wide report in 2026.
- NFL: the official weekly injury report on nfl.com, the final version for each week of the regular season. Where nfl.com gives a player no body part, it comes from the NFL's own practice-report feed, as copied by the open-source nflverse project. Return to play uses the NFL's official game books, which list every player who took a snap.
- MLB: MLB doesn't publish a daily injury report, so the site uses the injured list: every placement and activation from MLB's Stats API.
- MLS: the Player Status Report MLS publishes on mlssoccer.com before every matchday, since 2024.
- NWSL: the availability report the NWSL publishes before every matchday, 2025 on. The league keeps only the current report online, so the site saves it every matchday. The earlier reports come from copies, which miss some matches: the Wayback Machine's copies of the league's page, the league's PDFs on the Seattle Reign's press site, and word-for-word reposts by All For XI (X: @AllForXI, Instagram: @allforxi).
How injuries are counted
An injury is a run of games (NFL: weeks; MLS and NWSL: matches) in which a player is listed for the same body region; in MLB, one stint on the injured list. Teams describe injuries in their own words ("Left Ankle; Sprain", "knee", "Right elbow inflammation"), so each listing is grouped into one of 16 body regions, or illness. A listing that names only a general area, such as a bare "Leg", counts under the body part the team names in the listings around it, or as unspecified if it never does. Rest days, coach's decisions, personal reasons and suspensions are not injuries and are left out, as are listings marked not injury related even when they name a body part. A listing that names two body parts ("Knee, Ankle") counts as an injury to each. Each league's page explains its details, and every page offers its data as a CSV download.
Typical return to play
Each league's page also shows how long injuries keep players out, by body region and type of injury (sprain, strain, fracture, surgery and so on), over all seasons: the typical time out and the range for the middle half of players. Time out is counted in games for the NBA, WNBA and NFL, in matches for MLS and the NWSL, and in days on the injured list for MLB, and players still out when their season ended count as out at least that long.
