India captain Anil Kumble wants a second look at the system that allows a cricket player to challenge umpiring decisions.
"It definitely requires discussion," Kumble said Sunday after India won the second test against Sri Lanka by 170 runs.
"There are areas which really help the umpires but there are areas where it takes a longer time," Kumble said. "There is still some doubt whether someone looking at a television can make a call."
During the three-match series between the two countries, the International Cricket Council has allowed players to refer all on-field decisions to review by TV replay. Kumble questioned whether a TV umpire can accurately decide a leg-before-wicket dismissal.
Each side is allowed three challenges in each innings and the number of challenges remains intact if a decision is overturned using the system.
