The 12th Man in Cricket: What a Substitute Can and Cannot Do
The 12th man is cricket's substitute fielder — learn what they are allowed to do, what restrictions apply, and how the role has evolved with modern rules including the concussion substitute.
Who Is the 12th Man?
The 12th man is the first reserve player in a cricket team — one of the nominated squad members who does not make the playing XI but remains available to substitute field if a player is injured or taken ill during the match. They are not a playing member of the XI and cannot contribute to batting or bowling.
What Can a Substitute Do?
- Field anywhere on the field in place of the injured player
- Take catches, effect run-outs, and stop boundaries as a fielder
- The substitute does not bowl or bat under any circumstances
- The substitute cannot keep wicket unless they are the regular wicketkeeper returned to the field
What Cannot a Substitute Do?
A substitute cannot bat, bowl, or keep wicket. They are strictly a fielding replacement. If the original player recovers from their injury or illness, they can return to the field — but the substitute must leave. If a team wants a full replacement who can bat and bowl, they need a concussion substitute or an official ICC-approved replacement (depending on the circumstances).
The Concussion Substitute vs 12th Man
| Type | Can Bat? | Can Bowl? | Can Field? | Requires Approval? |
|---|---|---|---|---|
| Standard 12th man | No | No | Yes | No (injury/illness claim) |
| Concussion substitute | Yes | Yes | Yes | Yes — match referee |
Famous 12th Man Moments
Gary Pratt of Durham — a fielding specialist — became famous in the 2005 Ashes as England's regular substitute fielder, running out Ricky Ponting in a crucial Test. Ponting was furious, leading to a celebrated on-field confrontation with England's management — one of the defining moments of that Ashes summer.
Frequently asked questions
Can any member of the squad be the 12th man?
Yes. Any player in the touring or match-day squad who was not selected in the playing XI can serve as the 12th man substitute. Teams often nominate their best fielder as a dedicated substitute.
Can the 12th man keep wickets if the regular keeper is injured?
If the regular wicketkeeper is injured and must leave the field, any member of the playing XI can keep wicket — they put on the gloves and take over. The 12th man cannot keep wicket because they are not a playing member of the XI.
Has the ICC ever banned a substitute from fielding?
The ICC can investigate and penalise teams for misusing substitute fielders — specifically, using them without genuine injury grounds. While outright bans are unusual, match referees do monitor and challenge suspicious substitutions.
