The defender, who will now miss the club's next three games, appeared to headbutt Cheik Tiote after being robbed of the ball by a well-timed sliding tackle from the combative Newcastle midfielder.
"I received what I felt was a bad tackle from the player and that's why I reacted the way I did," Kaboul told Tottenham's official website.
"I know I should not do this and it's not in my nature.
"I apologise to my team and would like to say sorry to the fans and I hope we will not see that on the pitch again."
