THE Navua soccer side has become the first district to file a protest this year.
The protest is also the first since 2012 and was confirmed to Times Sport by Fiji Football Association CEO Bob Kumar.
Navua lost 0-2 to Lautoka last weekend at Ratu Cakobau Park in Nausori in the Fiji Sun/Skipper Tuna National Football League competition.
"Navua has filed a protest against Lautoka on the grounds of the eligibility of players," he said.
Since the protest fee has increased from $200 to $345 in 2012, no protests were lodged with the Fiji FA.
Meanwhile, Navua will face Labasa this weekend at the same venue and the Babasiga Lions are expecting a tough encounter.
Labasa FA official Edwin Chand said they knew Navua was hurting after the loss and would be out to get a win.
The Northerners won their last match 1-0 against hosts Rewa at Ratu Cakobau Park and are confident of another win on Sunday.
Chand said two players were expected to make their debut for Labasa this weekend.
"New signings Jesoni Takala and Epeli Loaniceva will boost our chances in the competition," he said.
"Two of our players have left already, Kavaia Rawaqa to Lautoka and Misaele Draunibaka to Rewa, and we expect the two new signings to be good replacements.
"Takala will definitely strengthen our midfield and we expect him in the starting line-up."
Chand said they hoped good weather would prevail this weekend.
"We had no problems in the North with the weather and we trained five days in a week.
"And we are hoping it does not rain this Sunday because it will be hard to play in the rain."
Labasa faces Navua at 3pm.
