Substitute Fielder in Cricket — Rules, Limits and Controversies
What is a substitute fielder in cricket? Learn when teams can use a substitute, what a sub fielder can and cannot do, and why substitutes have been controversial at the highest level.
A substitute fielder is a replacement player who takes the field when a regular member of the playing XI is temporarily unable to do so — typically due to injury, illness, or another off-field reason. The substitute can field anywhere on the ground but is subject to strict limitations: they cannot bat, bowl, keep wicket, or act as captain.
When Can a Substitute Be Used?
Under Law 24 of the Laws of Cricket, a fielding side may use a substitute if a player leaves the field for any genuine reason — injury, illness, attending to a need of nature, or another valid cause. The substitute must be approved by the umpires. Importantly, the substitute is permitted only to FIELD — they cannot bat or bowl under any circumstances.
What Substitutes Cannot Do
A substitute CANNOT: bat or bowl in the match, keep wicket, captain the side, or claim any wicket or dismissal on behalf of the substituting player. If a ball hits a substitute fielder intentionally preventing a run, the batting side is awarded 5 penalty runs. This rule prevents fielding teams from using non-playing specialists as fielding ringers.
The 12th Man Role
The '12TH MAN' (the first player excluded from the playing XI) is typically the designated substitute fielder for the team. They sit with the team, warm up, and are ready to take the field at short notice when a regular player needs a break. In hot conditions or long matches, multiple players may briefly leave the field for medical treatment — the 12th man may field in place of several players across a single day.
Controversies Around Substitute Fielders
Substitutes have been controversial when teams appeared to use them for tactical advantage rather than genuine medical reasons. The most famous incident came during the 2005 Ashes when England's Andrew Flintoff and others left the field and athletic substitutes took high-profile catches and took wickets as substitute actions — while the actual player was later seen apparently uninjured. Australia protested and the ICC subsequently tightened rules on when substitutes could be approved.
Concussion Substitute vs Regular Substitute
A CONCUSSION SUBSTITUTE (introduced in 2019) is different from a regular substitute. A concussion substitute can bat, bowl, and keep wicket — they effectively replace the concussed player entirely for the rest of the match. The regular substitute, by contrast, can only field. This distinction is critical: a concussion substitute is treated as a like-for-like replacement in terms of capabilities, while a regular substitute has no batting or bowling rights.
Frequently asked questions
Can a substitute fielder bowl in cricket?
No. A substitute fielder can only field — they cannot bat, bowl, keep wicket, or captain the side. This applies to regular substitutes under Law 24. Only a concussion substitute (introduced in 2019) can bat and bowl, as they are treated as a like-for-like replacement for a player diagnosed with concussion.
Who is the 12th man in cricket?
The 12th man is the first player excluded from the playing XI who serves as the primary substitute fielder. They sit with the team, warm up with them, and are ready to take the field when a regular player temporarily leaves due to injury or illness. They may also carry drinks and equipment onto the field during breaks.
