Leon Cameron has no doubts in-form run-with player Matt de Boer has the ability to contain Fremantle superstar Nat Fyfe, but the GIANTS coach isn't losing sight of the other Docker onballers in Saturday's clash in Canberra. 

Fyfe will make his return from a concussion against the GIANTS at UNSW Canberra Oval after he was ruled out of the Derby against West Coast.

De Boer has performed terrific shut down jobs on Tiger Dustin Martin and Cats pair Patrick Dangerfield and Tim Kelly in recent weeks.

But Cameron said de Boer wouldn't just put all his attention into Fyfe.

"Matty de Boer's greatest strength is his ability to play on two or three (players)," Cameron said.

"I know people will talk about what he's done over the last month, but it's not just on one particular player. He's played on (Tim) Kelly, (Patrick) Dangerfield and (Mitch) Duncan. They're all good, quality players. 

"Fremantle is no different. You've got (Nat) Fyfe, you've got (David) Mundy. You've got (Michael) Walters. You've got some really good kids coming through in (Andrew) Brayshaw and you've got the outside run of (Bradley) Hill and (Ed) Langdon.

"So, there's a number of players Matty will come up against and that's the thing we like about him is that he's really flexible."

Cameron said de Boer was in career-best form, with the GIANTS re-signing the former Docker until the end of 2020. 

"Not only does he play a really good defensive role at times. The thing I'm really pleased with is he's getting the footy as well and he's averaging 15 and 20 possessions so he's also adding to our offence," Cameron said.

"He's got a really steely mindset. He can switch out of playing a run-with role to playing a really attacking forward role, or playing on the wing or being a free-running midfielder. 

"He prepares to the nth degree, he's a true professional. There's a reason why we signed him up again last week, he's loving playing his footy at the moment.

"When a player is on top of his game there's nothing better to watch. But he also understands that last week's gone and he comes up against a pretty huge challenge against his old team this week." 

Canberra-born Jackson Hately, pick No.14 in last year's NAB AFL Draft, will make his debut in place of Callan Ward who will miss the rest of the season after rupturing the anterior cruciate ligament in his left knee. 

"Like every first gamer there's going to be some nervous times. There'll be butterflies in his tummy but as soon as he gets his first opportunity to impact the contest, I've got no doubt that he will," Cameron said.

"He's hard at it. He's got a little bit of that Callan Ward trait in him and he will tackle hard and put his head over the footy and that's what we like about him and he's got a good motor."
