Christophe Dominici has apologised for his error during France's 25-0 RBS 6 Nations victory over Italy.
Coach Bernard Laporte blasted the winger after he failed to touch the ball down properly and dropped it when five points could not have been more straight-forward.
"This is a gesture we cannot accept," Laporte said. "This was an unprofessional action and by doing that he lacked respect towards the whole team."
But Dominici has taken responsibility for his mistake.
"I wanted to put the ball down with only one hand as I usually do sometimes but I was carried away," the player added.
"I did not need to see the video to know that the try could not be allowed.
"What disturbed me the most is that I penalised the team when we could have led 20-0.
"I cannot explain what happened, I was on my own with no player behind me. This is probably a lack of concentration.
"If my try and that of Jean-Jacques (Crenca) had not been refused we could have won 39-0 and we wouldn't have had to face critics about the final score which is not wide enough compared to our domination on the match."
Scrum-half Jean-Baptiste Elissalde remains confident of RBS 6 Nations success despite Laporte's general criticism of the side.
Les Bleus are progressing well, second to England on points difference following back-to-back Stade de France wins over the Azzurri and Ireland.
Laporte was just one eminent critic who felt that France had failed to perform up to the required standard.
But Elissalde, who was celebrating his second cap, took things more positively.
"Of course we lacked efficiency throughout the match but it did not weaken us," he said.
"I am extremely confident in our potential because we created ourselves a lot of opportunities.
"It's like in a football match, a team can create 15 goal chance but manage to score only twice. There are days like that, when it simply does not get in.
