Injury Substitutes in Cricket: Rules and Limitations

Cricket's substitution rules are quite different from most team sports, with significant restrictions on what an injury substitute can do during a match. Understanding these rules is important for both players and fans who sometimes question why injured players appear to bat and bowl but their substitute only fielded.

The Fielding Substitute Rule

A fielding substitute may be used when any player is temporarily injured, ill, or otherwise unavailable for fielding, with the opposing captain informed before the substitute takes the field. The substitute can field anywhere on the ground but crucially cannot bat, bowl, act as wicketkeeper, or captain the team.

Why Substitutes Can't Bat or Bowl

The restriction preventing substitutes from batting or bowling preserves the integrity of the playing eleven as those selected before the match. Allowing substitutes to perform these functions would effectively let teams have more than 11 active players in key match situations, which would fundamentally alter the sport's competitive balance.

The Runner System (Largely Abolished)

Cricket used to allow injured batsmen to use a runner to physically run between the wickets on their behalf, a rule that caused considerable confusion and controversy over the years. The ICC abolished the runner rule for all international cricket from 2011, requiring injured batsmen to run for themselves or retire hurt.

Concussion vs Standard Injury Substitutes

The concussion substitute rule introduced in 2019 is fundamentally different from standard injury substitutes, as a concussion substitute is a full replacement who can bat, bowl, and field in all roles. The distinction matters because concussion substitutes are permanent replacements while fielding substitutes are temporary arrangements.
