Ruleset boundary
These procedures are competition regulations, not one universal tennis rule
The underlying play uses the 2026 ITF Rules of Tennis, but medical treatment, bathroom or attire breaks, code violations, electronic review, and match resumption are also controlled by the current regulations of the tour or tournament. For a 2026 Grand Slam, use the 2026 Grand Slam Rule Book; an ATP, WTA, ITF tour, collegiate, or national event may prescribe a different procedure. Name both the governing body and effective document before stating a time allowance or sanction.
Build a stoppage log with the score, server, time called, reason announced, official who authorised it, treatment or review start, and resumption time. This distinguishes a medical evaluation from a medical timeout and separates authorised treatment from an ordinary changeover. It also prevents broadcast time from being mistaken for the time kept by the chair umpire or supervisor.
Incident record
Keep medical, conduct, and review decisions in separate columns
A physical issue does not automatically decide whether conduct was unsportsmanlike, and a code sanction does not answer whether a line decision was correct. Record the rule family, warning or previous step, official announcement, and resulting score or penalty for each decision. For electronic review, identify the system and event procedure before assuming how many challenges remain or what happens when technology is unavailable.
If public information is incomplete, state the observable ruling and the applicable competition document without inventing a private diagnosis or an unannounced reason. That is especially important for medical incidents: the official match procedure can be explained without speculating about a player's health.
