Monster Yamaha Tech 3 boss Herve Poncharal was worried that out-of-work Gresini Honda riders Toni Elias and Alex de Angelis would take big risks to impress in Sunday's San Marino Grand Prix.
The warning proved partly correct when de Angelis slammed into the side of Edwards at turn two, bringing down Nicky Hayden in the process, clipping title rival Jorge Lorenzo and forcing Randy de Puniet off track.
The accident brought an end a 20-race run of points scoring rides by the Texan and cost him fifth in the world championship to Andrea Dovizioso, with four rounds to go.
"Colin had the pace for at least fourth position although you have to see the chequered flag to get a result,” said the Frenchman. “Before the race I sat down with Colin and told him that it looks good for him, but I was worried about the Gresini Honda riders who need to have good results.
“Alex de Angelis is a nice guy but this is not the correct way to go racing, he did not do it on purpose but this type of incident can be very dangerous. It is a pity because we have lost points in the team championship and now Colin is sixth in the riders' championship.”
Team-mate James Toseland was also held up in the incident, leaving him tenth at the end of the first lap, where he went on to finish.
“James lost ground early in the race. His lap times were very close to the battle for fourth and fifth place, but he had too much ground to make up. Now we cross our fingers for better results in the final four races,” said Poncharal.
Elias rose from fourth to second on lap one, and remained out of trouble on his way to sixth.
