The San Francisco 49ers have just been given a warning for a sideline incident, not a fine.

In the NFC championship game, someone on the 49ers' sideline collided with Seattle Seahawks special-teamer Jeremy Lane and knocked him down.

The league ultimately imposed no punishment for the hit. It may have been accidental.

The  precedent for a fine for an intentional sideline interference happened years ago when New York Jets strength coach Sal Alosi intentionally tripped Miami Dolphins cornerback Nolan Carroll.

The Jets were fined $100,000 and Alosi was fired.
