Dragons fullback Matt Dufty has jumped to his own defence as Paul McGregor swung the selection axe in response to the club's fourth straight loss.

Dufty and winger Mikaela Ravalawa were both left out of McGregor's 17 man squad which will face the Sharks on Sunday, a move which came as a surprise to the Dragons fullback.

Speaking before McGregor revealed his team to the squad on Tuesday, Dufty said the whole team must take responsibility for the dismal 45-12 loss to the Knights in Mudgee.

"We can be better. It was disappointing and embarrassing in ways," Dufty said of the loss to Newcastle. "We are all in it as a team. It’s a team game, it’s not just one person’s fault or one thing that led to the loss. We just have to come together and group as a team."
