INDYCAR has fined and placed Panther Racing CEO and managing partner John Barnes on probation through Dec. 31 for posting a comment using improper or disparaging language in reference to INDYCAR on his Twitter account pursuant to Rule 9.3.1.8 of the rulebook.

The amount of the fine is $25,000.

Rule 9.3.1.8 of the 2012 IZOD IndyCar Series rulebook: Using improper, profane or disparaging language or gestures in reference to Officials, Members or actions or situations connected in any way with INDYCAR, the IZOD IndyCar Series or any Event.

Barnes may contest the penalties pursuant to the procedures and timelines detailed in the rulebook. A protest/appeal may result in an increase, decrease or no change to the penalties.

Said Barnes in a statement: “Nobody cares about open-wheel racing and the Indianapolis 500 more than I do, and therefore I’m very passionate about all the decisions that are made – right or wrong – that affect our sport. I’m not the first person who has disagreed with a sports league or sanctioning body’s decision and I certainly won’t be the last to get fined for doing so. While my passion for this sport will never waiver, I should have chosen a more private forum to voice my opinions. Even if we don’t always agree, I respect the authority of the IndyCar Series and its officials and will continue to abide by their rules and regulations.”
