"It can happen, it's racing", he told reporters.
He said: "In my career I never, never, never go straight to one rider thinking that he will crash".
Marquez would then stall his bike.
An astonishing MotoGP race in Argentina yesterday was won after 24 dramatic laps by Briton Cal Crutchlow (LCR Honda) by a bike length from Johann Zarco (Tech 3 Yamaha) and Alex Rins (Ecstar Suzuki) to lead the world championship by three points from Andrea Dovizioso.
Apart from the podium finishers, the other rider who would be happy will be Andrea Dovizioso, as the Ducati rider had a poor outing in sixth place, but still leads Marquez by 18 points heading into the third race of the season in USA. With the race over, however, that was converted into a 30 second penalty, which moved him down to 18th, just one place ahead of Rossi.
Rather than argue in public with the world champion, the starter finally got the race underway.
"I stayed with riders I probably should have and would have been able to drop if I needed to". I approached faster than him and I didn't realise it. "You need to understand the track condition".
"I touched a wet patch, locked the front, and released the brakes". I tried to turn, again making my best effort to avoid contact.
Even without the drama of the Rossi-Marquez clash, the race was memorable enough. Because the press flocked to Marquez and Rossi after the Argentina Grand Prix, and many were missing from the post-race conference, the race victor, LCR Honda Castrol's Cal Crutchlow, had some negative words for the press.
Crutchlow looks to have found his ideal ride this season.
"In the afternoon, the second session was a bit odd as conditions were kind of mixed, but all in all we were able to do good work on the bike setup, getting a pretty clear idea about those conditions". Australian Jack Miller, riding a Ducati GP17 for satellite team Pramac Racing, alone at the front of the grid.
His frustration was understandable, but the story was undeniably elsewhere.
"I felt I could have ridden away from the rest but wanted to take no risks and save the tyres". So he went to his position because he thought the marshals were telling him to go there and nobody could take him out from that position and so that was the starting point to not a very good race. "He plays dirty", he railed.
"Of course today I did a few mistakes - a few of those mistakes were from Race Direction and a few were mine".
"I'm not race direction - they will decide - but like this he is destroying our sport, because when you do 300-kilometre an hour on the track, you have to have respect for your rivals".
