Substitute Fielders in Cricket: Rules and Restrictions
When and how substitute fielders are allowed in cricket, what they can and cannot do, and how the rules differ between injury substitutes and tactical substitutes.
Substitute fielders allow cricket teams to replace injured or ill players in the field without reducing the team to 10 fielders. However, the rules governing substitutes are deliberately restrictive — substitutes cannot bat, bowl, or wicketkeep, and their use is regulated to prevent tactical exploitation.
When Is a Substitute Allowed?
Under Law 24 (Substitutes), a fielding team may field a substitute for a player who is injured, ill, or 'for other wholly acceptable reasons' during the match. The substitute must be approved by the umpires. Crucially, a team cannot use a substitute simply because they want a stronger fielder in a key position — substitutes must be for genuine necessity.
What Substitutes Cannot Do
A substitute fielder can only field — they cannot bat, bowl, wicketkeep, or act as captain. Even if the player they are substituting for was scheduled to bat or bowl next, the substitute cannot take their place in those roles. The original player must return to bat or bowl themselves, or the team plays without those contributions.
The Super Sub (Discontinued)
In 2005–2006, the ICC trialled a 'Super Sub' rule in ODI cricket that allowed teams to make a permanent substitution (allowing the substitute to bat or bowl). The trial was quickly abandoned after it was widely criticised for distorting team balance and creating unfair advantages.
Abuse of Substitute Rules
Teams have been accused of using substitute fielders tactically — sending on their best fielder when a key position substitution is not genuinely needed. The ICC match referee can investigate and penalise teams for non-genuine substitution use. High-profile cases have involved fast bowlers being substituted off the field to rest during batting innings and returned when bowling resumes.
Frequently asked questions
Can a substitute fielder bat or bowl in cricket?
No. A substitute fielder in cricket can only field — they cannot bat, bowl, or wicketkeep under any circumstances. The player they are substituting for must return to bat, bowl, or keep wicket themselves when required.
What is a concussion substitute?
A concussion substitute is a special type of replacement introduced by ICC in 2019. If a player suffers a concussion during a match, they can be replaced by a 'like-for-like' substitute — approved by the match referee — who can bat, bowl, and field as a full replacement player.
When is a substitute fielder allowed?
A substitute fielder is allowed when a player is injured, ill, or unavailable for a genuinely acceptable reason. The umpires must approve the substitution. Tactical substitutions (replacing a weaker fielder with a better one without genuine cause) are not permitted under the Laws.
