The reigning double world champion and the eight-time title winner collided on lap 23 of 25 in Sunday’s grand prix at the Algarve International Circuit while battling over fifth place.
Marquez threw his Gresini Ducati up the inside of Bagnaia at the Turn 5 left-hander, but ran slightly wide.
As he tried to cut back to the racing line, Bagnaia moved to try to retake the position on the inside and the pair connected. Both crashed and failed to score, but the stewards elected to take no further action following an investigation.
Bagnaia accepts this verdict, but admitted to his frustration at tallying up a non-score in the second round of the season just as he did last year when he slid out of second in the Argentina GP.
“I was confident before the start because yesterday and this morning my feeling was good,” Bagnaia explained.
“I was feeling better with the grip and everything was better and better. So, I was thinking about a race of attacking and trying to have a good control of the tyres.
“But as soon as I started I was more in trouble, I expected to be faster and the guys at the front were too fast for me.
“So, I just tried to avoid everything, I was just trying to manage the tyres but [it] was difficult.
