There's been a late change of referee for Saturday's Rugby Championship opener between the All Blacks and Australia in Sydney with Frenchman Jerome Garces pulling out through injury.
Garces has been replaced by English ref Wayne Barnes.
The Frenchman was also down to be the assistant referee for the second Test in Dunedin.
Garces controlled the second Test between the All Blacks and the British and Irish Lions in Wellington last month.
He suffered a calf strain while refereeing last weekend and has been forced to withdraw.
He will be replaced for the game in Sydney by Barnes of England with Wales' Nigel Owens coming in as assistant referee.
The following week, Barnes will perform the role of assistant referee with Owens taking over refereeing duties.
