Injury to insult for Stade
Dupuy was helped off after only 16 minutes in their defeat against his former club, Leicester Tigers, and will be assessed next week. Quesada at least has a ready made replacement in the shape of Australian No.9 Will Genia, who arrived in the French capital last week.
"I'm confident in my team and I was pleasantly surprised at the way they played tonight. We have 15 players out with injury and there were a lot of players playing their first game of the season for us," said Quesada after the Pool Four defeat.
"We gave them a couple of tries which was quite frustrating – we gifted them a lot of points. But they did a good job and deserved their win.
"If we can keep that spirit and keep on playing like that we can be proud of it. We have to improve get rid of the stupid mistakes."
The French champions host Munster at Stade Jean Bouin on Sunday, November 22 in a game they will need to take some points from if they are going to challenge for a quarterfinal place in their first season in the Champions Cup.
