Officials with AMA Racing and the FIM (Federation International de Motocyclisme) have penalized Supercross class riders Joshua Hansen and Steve Boniface for their involvement in an altercation at the San Francisco round of the 2009 AMA Supercross, an FIM World Championship.

Both riders were found to have violated Appendix A, section A2.3j, of the AMA Supercross, an FIM World Championship, Rulebook, which states that the following offense is subject to disciplinary action:

"An attack on a Racing official and/or engaging in a fight. This includes any person who attacks or is involved in a fight anywhere on the premises prior to, during, or after an AMA Supercross, an FIM World Championship meet. There will be no maximum fine or suspension period for this offense."

Both Hansen and Boniface have been fined $10,000 for actions detrimental to the sport of motorcycle racing, with a probation until May 4, 2009.

If the rider remains in compliance, the fine will be canceled.

Should either rider violate the "AMA Supercross, an FIM World Championship Regulations" within the probationary period, then their fine will be due and the rider will not be allowed to participate in any future AMA/FIM events until the fine is paid.
