The NFL is trying to send a message to players after a tumultuous Week 2 in which the calls by replacement officials came under greater scrutiny and altercations broke out on the field.
According to the Baltimore Sun's Aaron Wilson, three Ravens players were fined for their play in last week's game vs. the Philadelphia Eagles.
Running back Ray Rice, right guard Marshal Yanda and cornerback Cary Williams were hit with penalties.
Williams' was the greatest at 10,000, and Rice and Yanda will pay 7,875.
Williams got into an altercation with Eagles receiver DeSean Jackson in the second quarter after a play while Yanda clashed with Eagles tackle Cullen Jenkins. Rice had a 15-yard flag for unnecessary roughness.
The league has sent warnings via memo to all 32 teams about respecting the officiating and not trying to bully them into making or negating calls.
Coach John Harbaugh has avoided questions about criticisms from his team about replacement officials since the 24-23 loss to the Eagles. Quarterback Joe Flacco, receiver Jacoby Jones, fullback Vonta Leach and linebacker Ray Lewis were among the most vocal ones.
