The Sheffield Wednesday head coach was fined £4,000 after clashing with Wanderers counterpart Phil Parkinson and handed a two-match touchline ban - after both were sent to the stands in the latter stages of the game on August 22 following an altercation emanating from Barry Bannan’s challenge on Filipe Morais.
Carvalhal was also engaged in a heated discussion with a steward as he attempted to take a seat behind the dug-out after the incident.
Carvalhal was subsequently charged with misconduct by the Football Association and found guilty at an Independent Regulatory Commission hearing.
Carvalhal, who will serve the second game of his touchline ban in tomorrow’s home game with Brentford, said: “I never felt a threat in a football game and I felt it, in that moment. I felt threat and fear.
“On the pitch, I did what I must do to protect my player. What I did was not correct. They gave me a two-game ban and I absolutely accept what happened on the pitch. After, when they put me in the stand, was very, very bad.
“Because I talk with different people now and also through social media, they told me that when they were at Bolton, they felt the same. It is better to take this into consideration in the future. I don’t think this solution is unique.
“I will protect myself after this moment because what happened in that game, I received a lesson. So, believe me, after this moment I will take a precaution.
“If another thing like this happens, I don’t want nobody touching me. I will try to be near the police to put me in the directors box as I must protect myself.”
