What is udrs decision in cricket?

Answer 1

UDRSstands for Umpire Decision Review System.Essentially, it is a challenge system for cricket. Due to its rather controversial nature, it is not universally sanctioned and generally reserved only for top-class competition such as Test Cricket.

Under the UDRS, if an umpire makes an "out" or "not out" call that a team feels to be in error, they can challenge to have the call reversed. A batsman, for example, may argue, that a slip catch hit the ground first, meaning he shouldn't be out. Or a fielding captain may challenge an umpire's call that a delivery was not LBW.

Once a challenge is acknowledged, the Third Umpire will review the play using only the basic technology at his disposal (which is typically limited to instant replays and the Hawk-Eye system). For an umpire's call to be overturned, the evidence must conclusively contradict his call-the umpire's original call gets benefit of the doubt. Once the Third Umpire relays his results, the field umpire will announce the results, either by re-signaling an upheld call or by revoking a reversed call and making the corrected signal.

The system is still evolving, but under usual circumstances, each team is allowed two challenges per innings, and a challenge is not lost if the result is a reversed call.
