Garreth Carvell has admitted that it is a case of being patient, as he waits to make his debut for the club while trying to shake off the effects of a knee injury.
“I’m hoping to back as soon as possible,” he said.
“There is no timescale on when that will be and it’s a bit of a waiting game at the moment with my knee.
“In the meantime I’m working hard with the reserves and also assisting Andy where possible with the first team whilst my injury clears up.”
Despite being unlikely to play in the game, Carvell is expecting Crusaders to give his team a real test in the clash in Wrexham.
“The Challenge Cup final is one of the highlights of the sporting calendar,” he added.
“The competition always throws up some David vs Goliath encounters and everybody always likes to the see the underdog win.
“We are under no illusions about Sunday and it will be a tough game. It’s important that the lads remain focused and that is what we have done in training this week.
“There’s no pressure on them but we have to concentrate on the task in front of us. Andy Hay’s created a game plan that ensures that if every player keeps to their job and we reach our potential it should ensure we go through to the next round.
They’ll have a lot of confidence but our away record in 2015 speaks for itself.
“We have a large squad at the club and a key motivation to perform well on Sunday is that if you don’t, there is somebody waiting to grab your place the next week.
“There’s fierce competition for places which keeps all players on their toes.
“The club as a whole also want to go as far as possible and hopefully in the next round draw one of the big boys at the Big Fella’s Stadium.”
