Sunderland will not face a points deduction from the Premier League in the continuing row over fielding Ji Dong-won with incomplete registration.

Press Association Sport understands 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.

Gaps in the 22-year-old Black Cats star's paperwork were highlighted following a routine drugs test, and the Premier League and Sunderland resolved the issues as a result.

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.

Sunderland forward Ji was correctly registered on arrival at the club in 2011, but issues arose after a loan spell with German club Augsburg.

Despite always being correctly registered with the Premier League and the Football Association, Ji's name was missed off a list of Sunderland players sent to world governing body FIFA for doping purposes.

Sunderland are thought to have reported this issue to the Premier League as soon as it was brought to their attention.

Press Association Sport understands the Premier League's investigation found that an online form had not been properly submitted to FIFA.

Sunderland are thought to have told the Premier League they submitted the form, but that a technical fault caused it never to reach FIFA correctly.

The Premier League board is understood to have determined that the technical nature of the oversight merited the fine meted out.

The Press Association understands no further action will be taken, despite two of Sunderland's relegation rivals making enquiries into the Premier League's disciplinary process.

Following Norwich's 0-0 draw at Chelsea, manager Neil Adams suggested the Canaries are assessing their options relating to Ji.

Adams said: "It's for the board. They'll look at it, I'm sure, but I wouldn't want to comment on that. It's not a football matter.

"But I'm well aware of what's happened. They're aware of it, and I'm aware that they're aware of it. But that's for them. My brief is football matters. That's the legal side."
