Canberra Raiders forward Clay Priest broke his ankle at training, ruling him out for the rest of the NRL season.
Priest, 27, has made 14 appearances for the Raiders in 2016, including in their 16-14 loss to the Cronulla Sharks last week.
But he broke his ankle at training on Wednesday, ending his season ahead of his team's semi-final with the Penrith Panthers.
The Raiders are still hopeful over the availability of Josh Hodgson, with the star hooker and Blake Austin to be given more time to prove their fitness.
A win for the Raiders at GIO Stadium would see them advance to a preliminary final against the Melbourne Storm.
