CATS and sharks clearly don't mix but Geelong coach Chris Scott says he'd risk open rebellion if he tried to ban his players from surfing.

The club confirmed key tall Lachie Henderson was surfing with former Carlton teammate Jarrad Waite at Bells Beach last week when a nearby surfer was knocked from his board by a shark.

AFL players are discouraged from taking part in activities that put them in harm's way, with some risky pastimes banned outright.

Several Cats players, including star recruit Patrick Dangerfield, take to the waters along Geelong's popular surf coast during the season.

But Scott admits he could have a mutiny on his hands if he tried to stop his players catching a wave in their down time.

"I reckon I would ... we've got a lot of surfers and it's an important part of their preparation," Scott said with a wry smile at a press conference on Tuesday.

"So I'll just try to not to think about the sharks."

The incident provided Scott with one of the more-bizarre scenarios a coach has had to deal with as he prepares his team for a preliminary final.

While several other surfers had the perfectly natural reaction of paddling madly for shore, Henderson and Waite remained in the surf.

"I was interested to hear that they stayed out there - I knew they were brave but I didn't realise they were that brave," Scott added.

"It probably suggests to me it was more likely a dolphin than a shark."

No one was harmed in the incident.
