Sydney Roosters will ask for a please explain over the number of five-day turnarounds they've copped as they join expressions of concern about next season's NRL draw.
Roosters chief executive Brian Canavan said he was "mystified" by his side's schedule which has them forced to back up in the space of five days four times in the first 20 rounds.
The Roosters join Manly who on Saturday voiced disquiet over their draw, saying their players' welfare was being put at risk.
The Roosters, Sea Eagles and Wests Tigers all have four five-day turnarounds in the first 20 rounds.
Canavan said his club would seek a meeting with the NRL this week for an explanation and to put forward their case.
"We're going to question about how these sort of things have arrived," Canavan said.
"We'll seek a meeting with the NRL to give us an explanation because we are mystified"
"Our sport science people have done research on (player burnout).
"The other aspect is if you play a number of these games with five-day turnarounds the performance levels drop as well because the players just aren't as energised or able to perform at their peak."
Canavan also took the NRL to task over the fairness of their schedule after the Roosters were drawn to play every 2015 top-eight side twice next year.
"We do appreciate the ratings consideration, but all we're looking for is greater fairness," Canavan said.
Meanwhile the Rugby League Players Association on Sunday slammed the NRL over the draw saying it was not consulted and the game's stars were being put at risk of injury.
RLPA general president Clint Newton decried NRL head of football Todd Greenberg's boast that five-day turnarounds had been kept level for next year's schedule.
Newton instead questioned why there had not been a reduction and whether enough was being done to prevent player burnout.
While the NRL has promised to reduce short turnarounds by a third in 2017, Newton said enough wasn't being done.
He said the player's union wanted a greater say in future draws after the NRL failed to deliver on its promise for greater consultation when the 2016 draw was being put together.
"The NRL want us to congratulate them because there has been no overall increase in five-day turnarounds but the reality is that for more of our members, the situation in 2016 is worse than in 2015," said Newton.
"The NRL says player welfare is a fundamental so why then are more players being expected to back up in five days in 2016 than in 2015?"
