Tomlin was handed a six-figure fine on Wednesday for his role during a game
between the two sides, in which he appeared to try to impede Ravens returner Jacoby Jones while he was running down the sideline.
When Smith was told of the amount that Tomlin has been asked to pay, he told reporters: "Oh! $100,000? That's tough. That's a lot of money. The incident is funny now because we won but if we'd have lost I admit that I'd have definitely blamed him.
"I can't say he did it on purpose though but it sends a message to the league. We can say he did it on purpose but we don't truly know. He did nothing crazy."
Smith also said that Ravens coach John Harbaugh will learn from Tomlin to make sure he never commits the same crime that his opposite number did.
"Coach Harbaugh stands right on that line," Smith added. "I think he'll be taking steps back now he knows that there could be a $100,000 fine coming his way!"
The Ravens won the game 22-20 and now have a 6-6 record in the AFC North.
