NADI referee Andrew Achari has been replaced on the Oceania Football Confederation Champions League referees panel after failing the fitness test.
Achari was one of the two local snamed for the group stage playoffs which started on Monday.
Fiji Football Association referee's director Paresh Kishore said Achari was reportedly sick when he underwent the first fitness test.
Kishore said Ravitesh Behari had been brought in as Achari's replacement. "Achari took the fitness test but could not complete and failed," he said.
"Achari was first tested on a Friday and then tested on Sunday and still he could not make it. So we had no option but to replace him with Ravitesh.
"Earlier Ravinesh Kumar our assistant referee from Nadi had been replaced by Rakesh Chandra of Lautoka. This is after Ravinesh pulled a calf muscle on the right leg during training.
"As FIFA referees, they should be on call 24/7. We called for the replacements and they passed the fitness test which is very good. They have done a marvellous job so far."
Achari became a FIFA referee in 2005 and officiated in the 2007 FIFA under-17 World Cup. He also officiated at the 2010 and 2014 World Cup qualifiers.
Chandra won the 2013 Fiji FA referee of the year award.
