The Yamaha rider was left incensed after being forced off the track by his MotoGP counterpart on Sunday.
Rossi was in sixth-place with just four laps remaining of the second race of 2018.
But the Italian was forced off the track onto the grass after Marquez knocked into him while going around a corner.
Rossi finished 19th, with his Honda rival one place ahead of him after he received a penalty.
But Marquez’s team are sticking by their rider.
“He had some space, if you check the TV he was not really on the limit,” said Puig.
“I mean Valentino also ran out a little bit.
“It’s not like Marc came in, in a position where there was another rider.
“Both riders went out a little bit and unfortunately Marc – due to this problem with the water – touched him and then Vale crashed on the grass.
“We understand it was a racing incident and of course we are very sorry for it.
“But of course, in this type of situation everyone has his own interpretation.
