The fine is imposed any time a team picks up six or more yellow cards in a match, but United will not face any disciplinary action after a number of players remonstrated with the assistant referee after Tottenham's goal.
Should six or more of their players be booked again in a single match this season then United would face a £50,000 fine.
Meanwhile, Rio Ferdinand has defended his actions after he and several team-mates confronted the linesman claiming Jermaine Jenas had handled in the build-up to Dimitar Berbatov's goal.
Ferdinand told the Manchester Evening News: "I thought they were fortunate with their goal. It was handball and how the linesman didn't see it I will never know.
"I was behind it and I could see it and I don't know how the linesman didn't. That's why I was remonstrating with him.
"I thought he handled it. Owen [Hargreaves ]would have cleaned up if he hadn't hit the ball with his hand and then it led to the cross and the goal."
