The Knights could be without Jackson Hastings for their do-or-die final against the Warriors after their go-to halfback failed to take part in the second half of Sunday's clash with the Raiders.
In Newcastle on Sunday, Hastings returned from a three-match stint on the sideline due to a syndesmosis injury, but the rugby league journeyman was ruled out of the game at half-time after reaggravating his ankle issue.
The Knights won their first finals match since 2013 in front of an electric sell-out crowd, defeating the Raiders 30-28 in an extra-time heartstopper, but Hastings might not be fit to play as Newcastle shoots for a preliminary final berth in Auckland on Saturday.
