The uncertainty around how financial rule breaches are handled "makes a mockery of the Premier League", says Luton Town midfielder Andros Townsend.
Everton were docked two points for a second violation of the Premier League's profit and sustainability rules (PSR) on Monday.
They say they will appeal against the decision but the process may not be completed before the season ends.
That could leave clubs uncertain of their top-flight status after 19 May.
PSR rules permit clubs to lose £105m over three years and Everton were found to have breached that by £16.6m for the three-year period to 2022-23.
