Geelong coach Chris Scott hopes one veteran has avoided serious injury while dismissing concern over another after a shock defeat to Port Adelaide.

Utility Mark Blicavs will have scans after hyperextending his left knee in the 13.17 (95) to 10.5 (65) loss on Saturday night.

But Scott says there's no injury worry over captain Patrick Dangerfield, who collected only four disposals in the game.

"We had 23 (attacking) entries at three quarter-time. He was a forward 50 player, so the ball wasn't going to him very much," Scott said of the Brownlow medallist.

"We actually thought he looked sharp this week.

"But he wouldn't be the first player, and he won't be the last player, that had a long lay-off, came back, played pretty well first up, and was a bit rusty on his second run.

"That's a bit of a cliche and maybe a little bit of a cop out but it seems like that was the case. We'll wait until we see what we get next week."

The Cats boss was hopeful Blicavs only faces a short stint on the sidelines after hurting his left knee.

"The medics are hopeful it's not serious," Scott said.

"He was pretty upbeat as well, but he's - you know the Monty Python skit, he could have his arm chopped off and he'd still be positive about it, he's that kind of guy."

The Cats slipped to a four-three win-loss record after a lacklustre display, but Scott said he won't be "jumping at shadows" in response.

"It was difficult to explain our performance ... the final margin was 30 points, but it should have been 60," he said.

"The challenge is trying to work out what are real issues that need to be addressed, and what are fleeting things that you can move past pretty quickly.

"I'm a big believer in the game, full stop, but especially knowing our group so well, that you shouldn't jump at shadows.

"You don't want to wait too long but you do need to see a pattern before you before you make big changes.

"Without being too flippant about it, I think it's likely we will stay positive and try to forget that one as quickly as possible."
