DRS system for No-Ball
What Is the DRS No-Ball System?
The Decision Review System (DRS) is used to support umpires by using technology to review key decisions.
For no-balls, DRS mainly focuses on front-foot no-balls and dangerous height-related no-balls.
The goal is to improve accuracy, fairness, and player safety while reducing human error.
Front-Foot No-Ball Detection
Front-foot no-balls are checked automatically using Hawk-Eye and broadcast cameras.
The system monitors the position of the bowler’s front foot at the exact moment the ball is released.
A delivery is ruled a no-ball if any part of the front foot lands beyond the popping crease.
This check happens in real time, so the on-field umpire does not need to make the decision manually.
The third umpire communicates the decision to the on-field umpire almost instantly.
If a no-ball is detected, the batter receives a free hit (in limited-overs formats).
Height-Based No-Ball Reviews (Waist-High Full Toss)
Teams are allowed to review waist-high full-toss no-ball decisions.
Ball-tracking technology is used to calculate the height of the ball when it reaches the batter.
The batter’s actual position and movement at the crease are taken into account.
If the ball is above waist height at the popping crease without bouncing, it is ruled a no-ball.
This prevents batters from unfairly stepping across to manufacture a no-ball.
Other No-Ball Considerations
DRS may also assist with reviewing:
Above-shoulder bouncers
Dangerous short-pitched bowling
Final decisions depend on playing conditions and match regulations.
