The potential swap of players could instigate a first round match-up where the Dragons and Tigers face off.
Matterson and Leilua are both currently under contract which can complicate the deal but Tigers believe if the right compensation on a playing or financial basis.
Matterson has recently been excused from training commitments due to “personal reasons.”
Leilua has made 43 NRL appearances but is yet to nail a consistent starting spot in Coach Paul McGregor’s side, which could fuel a potential move for the 23 year-old.
Due to a salary cap squeeze, Tigers coach Michael Maguire is assessing all his options to offload talent to release the cap pressures. other than Leilua, Maguire is also contemplating the acquisitions of Titans Utility, AJ Bronson and Cronulla star, Matt Moylan.
