Out-of-contract forward Lachie Henderson is keen on re-signing with Carlton, despite holding off putting pen to paper on a new deal.

Blues football operations manager Andrew McKay said Henderson had delayed inking a new contract to focus on his football in the early stages of the season.

But McKay said the club wasn't at an impasse with the former Brisbane Lion and talks were progressing well with Henderson's management group.

"I spoke to the management group again this week. They're all very comfortable with Carlton and there's no worries about Lachie going anywhere else," McKay told Crocmedia.

"They're just sitting down for another couple of weeks and then we'll assess it from there.

"We've been in constant conversation with Lachie's management and a number of weeks ago they said let's see how Lachie starts playing early on in the year and then we'll look at in the next couple of weeks. That was six weeks ago."

Meanwhile, ruckman Matthew Kreuzer will resume training with the main group next week as he recovers from a foot injury.

Kreuzer suffered a hairline fracture in his foot during pre-season training in February.

McKay said the luckless Kreuzer, who is also out of contract at season's end, will return through the VFL with the Northern Blues before being considered for a senior recall.

"He's running and he'll start training next week. I take my hat off to Matthew. His attitude has been absolutely first rate," he said.

"It was obviously devastating to hear that news for him – and for us of course – a month or so ago, but he's been so positive since that period. He's just itching to get back out there."
