What happens if a squash player is injured during a match?

• Illness: cramp, nausea, a blister, breathlessness or asthma. The player must "either continue play immediately or concede the game in progress".
• After conceding a game: the player takes the interval, then resumes or concedes the match.
• Genuine or not: the referee decides whether an injury is genuine and announces its category.
• Self-inflicted: a muscle tear, a sprain or a bruise from hitting a wall or falling. "Up to 3 minutes".
• Still not ready: the player concedes that game and takes the interval, then resumes or concedes the match.
• Contributed: accidental action by both players. "Up to 15 minutes", then resume or concede the match.
• Opponent-inflicted, accidental: up to 15 minutes. If the player cannot resume, "the Referee must award the match to the injured player".
• Opponent-inflicted, deliberate or dangerous: if any recovery time is needed, the match goes to the injured player.
• A recurrence: no new time. Play on, or concede the game.
• Conceding keeps the score: a player who concedes a game or match keeps the points and games already won.
• The player decides: "It is always the injured player's decision whether or not to resume play."
• Unplayable court: if a player's vomiting makes the court unplayable, the match goes to the opponent.

The glossary has the referee, the interval entry, the game, the match, the conduct penalties entry and the blood injury entry.

Fitness is part of squash, so running out of it, including cramp, earns no pause. The sliding scale for injuries follows responsibility: a player bears the cost of their own fall and shares it for a collision. They are protected when the opponent alone was the cause.
