Second-rower Joseph Tapine will miss the remainder of the 2018 season due to a broken thumb.
Tapine will join trio Jarrod Croker, Jack Wighton and Ata Hingano on the season-ending injury list as Tapine will be looking for a quick recovery in order to begin pre-season for the 2019 competition.
In 2018, Tapine managed 16 games for the green machine, scoring six tries, making 586.1 post contact metres and having a total of 1489 running metres.
Winger Michael Oldfield will continued to be observed this week in order to make his return to the field from a knee injury.
Oldfield was last week named in the extended squad and this week will be pushing for a position in the final 17.
With the Raiders not featuring in finals for 2018, they’ll be looking to finish the season off on a positive note in their final two games against the Rabbitohs and the Warriors.
