The Canberra Raiders' top 30 squad might be full, but they have the salary cap space and ability to sign a couple of players if they pop up.
While the Green Machine published a senior roster of 29 on Monday, they have added Samoa hooker Danny Levi on a two-year deal.
That nominally completes their top 30, but they do have the flexibility to re-classify some contracts to open up room in the top squad.
Trevilyan's knee injury was the catalyst for Levi's addition to the squad to ensure Tom Starling and Zac Woolford weren't Canberra's only dummy halves in the squad.
