Why IPL Umpires Change the Ball — Replacement Rules in IPL 2026

If you have watched any IPL 2026 night match you have probably seen the umpire reach into a small box, pull out a ball, hand the bowler a different one, and play on. IPL ball replacement rules 2026 are governed by ICC Law 4.5, BCCI playing conditions, and a dollop of umpire judgment. Here is exactly when umpires switch the ball, why, and what captains like Axar Patel, Jasprit Bumrah and Pat Cummins keep asking for.

TL;DR — When the Ball Gets Changed

Reason	Trigger	Rule
Out of shape	Fails the ring/gauge test	ICC Law 4.5
Lost	Cannot be found in fielding restriction time	Umpire discretion
Damaged	Visible split or cut	ICC Law 4.5
Dew-soaked / wet	Cannot be gripped or dried	BCCI playing condition
Tampering suspected	Marked for forensic check	Match referee

ICC Law 4.5 — The Replacement Rule

ICC Law 4.5 says the umpires have the discretion to replace a ball that has become unfit for play. Unfit means out of shape (fails the gauge), visibly damaged, or significantly altered in some way that affects the contest. The replacement ball must be of similar wear to the one being removed — the umpires keep a box of pre-worn balls precisely for this reason. Captains can request an inspection but cannot mandate a change.

The Ball Gauge — How Umpires Actually Test

The ball-gauge test is simple. The umpire holds a metal ring of fixed inner diameter. The ball must pass through cleanly. If the ball is even slightly oval and snags, it is out of shape and must be replaced. The test takes seconds and is done in plain sight — usually after the bowler complains that the ball is going off line for no apparent reason.

Dew-Soaked Replacement — The IPL-Specific Rule

This is the IPL playing condition that does not exist in red-ball cricket. In second-innings dew, the ball can become unmanageably wet. Standard practice now: umpires use a towel break, then if the ball still cannot be gripped, swap it for a comparable-wear replacement. This is the most common reason for a mid-innings ball change in night matches — and is the rule captains like Axar and Cummins routinely demand the umpires apply more aggressively.

New-Ball Clauses — Why the Two-Ball Rule Matters

The IPL uses two new white balls per innings — one from each end. This is to combat ball discoloration in night conditions. Each ball is roughly 10 overs old at any point in the second half of the innings, which limits reverse swing but improves visibility. For everything new-ball-related, our new-ball rules guide lays out the full framework.

Captain Requests — What Captains Can and Cannot Do

A captain can ask the umpire to inspect the ball at any time. They cannot demand a change. The umpire's decision is final — and unlike DRS, ball replacement is not reviewable. Repeat unjustified requests can be flagged as time-wasting and contribute to slow over-rate penalties.

Outlook — Will the Rules Change?

The dew problem keeps growing as the IPL window shifts and pitch surfaces evolve. Expect a 2027 BCCI review of the dew-replacement protocol, possibly to include a permitted oil-and-towel treatment that does not currently exist in the rule book.
