Wolves manager Nuno Espirito Santo has been fined £25,000 and warned as to his future conduct following recent remarks about referee Lee Mason.
Nuno claimed Mason was not good enough to officiate in the Premier League following his side's 2-1 loss to Burnley on December 21.
The Football Association announced that the Wolves boss has accepted a charge of improper conduct following a personal hearing.
A statement from the governing body read: 'The (Wolves) head coach admitted that comments he made during a post-match interview constitute improper conduct as they were personally offensive to the match official and bring the game into disrepute contrary to FA Rule E3.
