Sunderland will not suffer any points deduction over the Ji Dong-won affair.
PA Sport says the Premier League is confident any issues regarding Sunderland striker Ji's incomplete registration were resolved as soon as they were uncovered.
Fulham and Norwich are understood to have contacted the Premier League for clarification on the fine handed to Sunderland over fielding Ji for four games without full registration.
The Premier League remains comfortable with the punishment handed out to Sunderland, and is not thought to believe any legal challenge can be mounted against the decision.
