FORMER Great Britain hooker Lee Jackson will be given a late fitness test before York coach Richard Agar can finalise his side for Sunday's clash with the Giants.
The vastly-experienced Jackson, who won an Australian NRL Grand Final medal with Newcastle Knights seven years ago, has been struggling with a shoulder injury which forced him to miss last week's 36-12 defeat at Batley.
Also missing that day were former Giants centre Chris Langley (back) and Damian Ball (shoulder).
But there is every sign that they will be available to play in York's biggest game for years, with Agar keeping his fingers crossed that captain Jackson will be alongside them.
"At this moment I've 19 players to choose from, which is a bit of a luxury because we haven't had the best of luck on the injury front," revealed Agar, who has Dan Briggs as another possible doubt with a leg strain.
"I'm obviously keen for Lee to play if at all possible. His wealth of experience at the highest level is crucial.
"That's why I intend to give him until the last minute to prove his fitness.
"But whoever I pick I am sure they will play with bags of enthusiasm and will enjoy Sunday's experience."
Former York captain Richie Hayes will come out of retirement for a second time and play through the pain barrier.
The long-serving prop, who recently celebrated his 34th birthday, officially hung up his boots following York's third-round win over Villeneuve but came back to help them out of an injury crisis for their fifth-round tie at Featherstone.
