The Cowboys will be hoping their confidence-boosting win over the Knights will translate to a lift in their attack when they take on the Sydney Roosters on Saturday night.
Cowboys coach Paul Green is hoping the confidence the team picked up will lift all his players, especially all-time great Johnathan Thurston.
"It's been a struggle for him [Thurston] at different times through the year, as it has been for all of us. I think he would have taken plenty out of that, personally, last week and he'll take that confidence into this week," Green said.
"I think the boys had a good week and it's just nice to get a win, it's been a while between wins so the boys really enjoyed it," Green said.
The Cowboys scored four tries in the win over Newcastle - the most in seven weeks or since May in their round 13 win over Manly.
"The way we won too, we had to show a bit of character, it wasn't our best performance by any means but we still fought hard to get the win so it's about building off that and taking that confidence into next week," Green said.

"We're confident going into every game but our form probably has been better against the better teams so we need to go in with a confident attitude and play our best footy."
While the Cowboys are eager to put a string of wins together to close out the season, they have no doubt it won't be all about them at Allianz Stadium on Saturday night.
After the Roosters knocked over the Dragons last round Green acknowledged that their opposition wouldn't be laying down to give Thurston a more positive end to his career.
"There's obviously some good players in their team that we need to be aware of, each week is a balancing act between worrying about yourselves and the opposition," Green said.
"If you spend too much time on them you forget about what you do right and for us it's probably about building a bit of confidence off last week."
