The title-chasing Parramatta Eels may need a special dispensation to field a full team against the Warriors this weekend.
And rival clubs are furious that the Eels have forced the NRL into a tricky positon, after ignoring a directive related to Covid-19.
The Warriors are scheduled to play the Eels on Sunday, in the Brisbane-based Magic Round.
Parramatta ignored an NRL directive designed to protect the biosecurity bubble before all the teams headed to Queensland, which has strict border rules.
The Eels decided to use its fringe players in reserve grade - which is outside the bubble - during the last round. As a result, they face a shortage of first grade players due to injury and suspensions.
