Rauf stands in for sick Benson

Asad Rauf has gone from TV umpire to on-field official for the second day of the Adelaide Test after Mark Benson was unavailable due to being "unwell". Benson stood with Ian Gould on the opening day but the match referee Chris Broad confirmed on the second morning that Benson was unable to take his place.

Bruce Oxenford had been the fourth umpire and was duly promoted into the TV official's chair, while Andrew Collins was brought in as fourth umpire. Oxenford was in the action immediately as he upheld Gould's lbw decision from the first ball of the day after Darren Sammy asked for a review.

It had been a challenging opening day for Benson, who was asked to make several tight decisions and twice had his not-out caught-behind calls for Shivnarine Chanderpaul reviewed by the Australians. Both were close decisions and Rauf gave the first not out but overturned the second call, sending Chanderpaul on his way.

It is not the first time Benson has been unable to take his place on the field. He was to officiate in Australia's recent one-day international series in India but was taken ill on the eve of the first match, leaving two Indian officials in charge, and did not take any part in the series. Benson was also forced to leave the field during a Test in Durban in December 2006 due to heart palpitations and he later had minor heart surgery.
