Mitchell Moses will have to wait at least one more week to play for Parramatta, with the star five-eighth unable to secure a release yesterday.
Wantaway Moses was named as part of the Tigers' 21-man squad for their clash with the Bulldogs, after yesterday's 4pm deadline for this weekend passed without a release.
It meant Parramatta were unable to select him in their extended squad for Saturday's match with Penrith.
Under the NRL's new team-list guidelines, coaches can only select from the 21 players named on Tuesday in a bid to uphold the integrity of the game.
The NRL drew a line in the sand earlier in the season when they refused to allow mid-week recruit Dale Copley to run out for the injury-ravaged Gold Coast - a precedent that will end any hopes Brad Arthur had of immediately piloting Moses into his halves. The Tigers are refusing to let Moses go without a fight and are understood to be playing hard ball with Parramatta over their negotiations for the 22-year-old.
