RISING Geelong star Jordan Clark's season is in doubt after he injured his left elbow in a training mishap on Wednesday.

Clark was taken straight to hospital for scans in obvious pain and with his arm in a sling, having landed awkwardly after a marking contest with ruckman Zac Smith.

The 18-year-old has already been ruled out of Saturday's home clash with North Melbourne and could face a significantly longer stint on the sidelines depending on the results of the medical scans.

FULL INJURY LIST Who's ruled out and who's a test?

Jordan Clark is helped from the field after his injury on Wednesday.



Clark has played 18 matches in a hugely successful debut season after being picked up by the Cats with pick 15 in last year's national draft.

Geelong will now make at last two forced changes - and probably further unforced ones - to the side that lost by 34 points to Fremantle last weekend, throwing the race for the minor premiership wide open.

Forward Gary Rohan is set to miss the next two rounds with a knee injury.

Speaking before training at GMHBA Stadium, coach Chris Scott said impressive midfielder Brandan Parfitt was likely to return to the side to take on the Kangaroos having overcome a back problem.

Luke Dahlhaus, Mark O'Connor and Harry Taylor are also probable inclusions to the line-up.

The ladder-leading Cats have dropped four of seven matches since the bye and are now ahead of West Coast and Brisbane on percentage only.

"It's not as though we've lost four in a row, either," said Scott.

"We're far from panicking around the way we're going.

"We've got a high level of confidence that we can find our best football and that our best football competes pretty well with anyone.

"But it's not to say that we don't have things to work on because we do.

"The specific part of the season now for us is that we had a little bit of room to move a couple of weeks ago and now we don't - which might not be the worst thing."
