Marco Simoncelli says he will ride more carefully in future after being warned over his actions at the French MotoGP.
Repsol Honda's Dani Pedrosa will miss Sunday's Catalunya MotoGP with a broken collarbone after a collision with Simoncelli at Le Mans last time out.
A statement from race direction said Simoncelli "recognised that he had made an error of judgement".
It added: "He stated that in future he would try to evaluate situations better and be a little more cautious."
The riding style of Simoncelli, who is considerably taller than many other MotoGP riders, has drawn critcism this season from world champion Jorge Lorenzo.
Simoncelli - who like Pedrosa is a Honda employee, for a satellite team rather than the main factory one - was punished with a ride-through penalty at Le Mans, which cost him what could have been a podium finish.
He initially protested his innocence over the Le Mans incident before toning down his comments and conceding that "on reflection, I have realised where I have gone wrong and in the future I will try at certain times to evaluate the situation better".
Simoncelli also moved to pre-empt a hostile reception in Catalunya this weekend, having ruled out one of the home favourites, admitting that he was "probably not going to get a standing ovation" from spectators.
But Lorenzo has moved to defuse the situation, appealing for fans "not to make an exaggeration of the situation".
Pedrosa's injury to his right collarbone, coming shortly after he had surgery to remedy ill-effects caused by a broken left collarbone last year, has dealt a blow to his world title chances.
After four races Lorenzo leads the championship on 78 points, with Casey Stoner second on 66 and Pedrosa in third on 61.
