GEELONG is confident a bout of glandular fever won't have too much of an impact on the pre-season of its first-round draft selection Jordan Clark.

Clark was diagnosed with tonsillitis and glandular fever recently, with clubs only informed about his condition late last week.

Cats list manager Stephen Wells said the club did not take into account the prospect of its No.15 pick having a delayed start to the pre-season when they decided to choose him, believing the issue to only be a "short-term thing".

Clark, who will visit Geelong for the first time on Monday, said the illness had not had too much of an adverse affect on his training program.

"I'm fine, obviously it's not the best scenario to be in but I definitely wasn't knocked around too heavily from it," Clark told AFL.com.au.

"It was a bit exaggerated through the media but definitely not anything severe to worry about at all. It was more getting over the tonsillitis that I had."

Clark will meet with Geelong's doctors on his first day at the club on Monday and work out a plan going forward.

"I'd love to start training day one, but for my own personal benefit it will be about easing me in," Clark said.

"Because I haven't done anything for a long time and I still feel a little bit drowsy here and there, but nothing too major at all."

Clark only made the decision to forgo a promising cricketing career four months ago and Wells said it was a situation his team had monitored closely.

Clark played for Australia's under-16s team against Pakistan in Dubai last year. The quick seam baller picked up a hat-trick in a one-day game against Pakistan and finished with figures of 5-37.

But he said the decision he made to concentrate on football was made relatively easy by how his year played out.

"We were very pleased to be able call Jordan's name out. His numbers were compelling at under-18 level and also when he played some senior footy at Claremont," Wells said.

"When it came to our selection we had great delight in calling his name out."

Clark can find the ball – he averaged 20 disposals and nearly six rebound 50s across the championships – and he reads the play well to cut off things and start them for his side. His performances at senior level were also strong, averaging 15 disposals over five games.

He loves to attack with dare from half-back and use his penetrating right boot to move the ball up the field, and the thought at this stage is that he has the capability to slot into AFL level straight away.

"It won't hurt him that he played senior footy at Claremont, but it will depend on his form and how everyone else is going," Wells said.
