Raiders captain Jarrod Croker has claimed that the green machine have taken a lot of confidence from the previous couple of weeks as his side prepare to face the Rabbitohs in Gosford this weekend.

"Obviously you get a bit of confidence after a couple of wins but it's a big challenge for us this week," Croker said.

"Our defence has been really good for the past couple of weeks and we know we will have to back that up again this week."
