The International Cricket Council (ICC) is trialling a new review system, called Officiating Replay System (ORS), in which a non-match umpire is provided with direct replays during a match.

Simon Taufel, who retired from umpiring after the World Twenty20 in October, was speaking Wednesday while delivering the 13th MCC Spirit of Cricket Cowdrey Lecture at Lord's, said the ongoing Ashes series between England and Australia "highlights one significant challenge -- that of succession planning".

The late British cricket journalist Christopher Martin-Jenkins gave the lecture six years ago, with former Anglican bishop Desmond Tutu following suit in 2008.

Simon Taufel and Aleem Dar would be officiating in the World T20 final between West Indies and hosts Sri Lanka in Colombo on Sunday.

Bruce Oxenford will be replacing Simon Taufel on the Emirates Elite Panel of ICC Umpires from November 1, the ICC announced on Wednesday.

Simon Taufel will step down from the Emirates Elite Panel of ICC Umpires after the World Twenty20 in Sri Lanka, which runs until October 7, to take up the new role of Umpire Performance and Training Manager, the ICC said on Wednesday.

Four ICC Elite Panel umpires will officiate in the play-off matches of the Indian Premier League.

A major controversy erupted in the tri-series match between India and Australia at the SCG, with Sachin Tendulkar being dismissed in a debatable run out and visiting captain Mehendra Singh Dhoni lashing out at pacer Brett Lee for standing in the way of the batsman.

Australian Simon Taufel and Pakistan's Aleem Dar, who officiated in the World Cup final between India and Sri Lanka last week, were on Thursday named among 17 on-field umpires for the fourth edition of the Indian Premier League commencing on Friday at Chennai.

Umpire Simon Taufel has apologised to Umar Akmal after footage replays confirmed that the Australian erred in ruling him out at the Champions Trophy.
