Meanwhile Matterson's move to the middle is paying dividends.
The Eels junior grew up as a five-eighth, and is able to see his role in the middle as similar to that.
"I'm more involved," he said.
"I get my hands on the ball a lot more and I get to choose whether to run or pass.
"Back row at the moment people are running lines and you're a bit more of a crash player. But I enjoy being a ball-player."
His shift from edge to middle came after raising the topic with coach Brad Arthur early in the pre-season, with Matterson having toyed with the idea for the past two years after being signed as an edge.
"Brad said 'I am glad you said that, because I was thinking the same thing'," Matterson said.
Parramatta will meet with Ryan Matterson's management in the next fortnight as the Eels begin their fight to retain the off-contract back-rower.
