Reviews, UltraEdge, and “umpire’s call” — a constant rules search. This page has 50 important questions and answers.
The Decision Review System (DRS) lets a team challenge an on-field call using TV, ball-tracking, and edge detection. Each team has a limited number of unsuccessful reviews. “Umpire’s call” on LBW means the original decision stands if the ball is only clipping the zone the protocol names.
DRS is not used in every domestic game. Soft-signal rules for catches have also changed over time — use the current playing conditions.
