How the DRS Review Process Works Step by Step
When a player wants to challenge an umpiring decision, a specific process unfolds. Learn the exact sequence of a DRS review from appeal to final verdict.
Step 1 — The On-Field Decision
The on-field umpire makes a decision — typically out or not out on an LBW appeal or caught-behind. The fielding captain or the dismissed batter must decide within a few seconds whether to challenge.
Step 2 — Requesting the Review
The challenging team signals the review by forming a 'T' shape with their arms or hands. This must be done before the umpires move away from the stumps or the next ball is bowled. The umpire acknowledges and the on-field play pauses.
Step 3 — Third Umpire Investigation
The third umpire checks the relevant technology: Hawk-Eye for LBW trajectory, Ultra Edge for edges, or multiple camera angles for run-outs and catches. They assess each criterion in sequence and communicate findings to the on-field umpire by earpiece.
Step 4 — The Verdict and Its Impact on Reviews
| Outcome | Review Retained? |
|---|---|
| Decision overturned (reviewed team correct) | Yes — review retained |
| Decision upheld (original umpire correct) | No — one review lost |
| Umpire's Call (too close to change) | Yes — review retained |
Step 5 — On-Field Signal
The on-field umpire signals the result to the crowd using the standard out or not-out gestures. The TV replay of the third umpire's analysis is shown on the big screen. Play resumes — either the dismissed batter returns to the crease or the next batter comes in.
Frequently asked questions
How long does a DRS review take?
Most reviews are completed within 60 to 90 seconds. Complex caught-behind decisions that require multiple technology checks occasionally take longer.
Can the fielding captain review a not-out decision?
Yes. The fielding captain can review any dismissal decision — out or not out — using their allotted reviews. They too must signal within the time window before play resumes.
What happens if a team has no reviews left?
The on-field umpire's decision is final and binding. Neither the batter nor the fielding captain can challenge it without a review to use.
