Marc Marquez has been given one penalty point on his licence for the incident with team-mate Dani Pedrosa following the incident at Aragon's MotoGP round, which takes him up to three.
It means he is now up to three points and adding a fourth this season will mean an automatic back-of-the-grid start. Race direction have have also removed the constructors' championship points won for Honda by the Spaniard.
"We are sending a message to Marc, very clearly, that we understand that he is an extremely talented rider but he is also intelligent enough to understand that there has to be some margin for error – especially, as we have seen a number of times this year, under braking when the rider behind has the responsibility of not getting too close to the rider in front who is riding his own lines," said race director Mike Webb.
"Finally, we have had an incident in which Marc has been very close to another rider – close enough to make contact – when coming from behind under braking. For us, that is a signal to make a formal warning by way of a penalty point to Marc to say he has to take more care."
