Brisbane Lions National Talent Manager Rob Kerr says the Club has almost reached a deal that will see Sam Docherty join Carlton during the Gillette AFL Trade Period.

"Carlton's leading the charge there," Kerr told SEN on Wednesday morning.

"They've put an offer on the table and have been pretty strong in their interest with Sam. They're certainly sitting in front there. We're probably at the point where we've just about got an agreement.

"I'd like to see how the other trades fall out and what that might mean in terms of picks and shuffling of picks before we make a firm commitment."

Jared Polec is also in demand, with both Adelaide and Port Adelaide scrambling to get a deal done with the Lions.

"It's fair to say both clubs are working pretty hard to try and get a better draft pick than what's currently on the table," Kerr said.

"Adelaide have got players but not draft picks at this point, and they're talking to other clubs about trying to get another pick that might satisfy.

"There's good competition between the two clubs."

Billy Longer may yet stay at the Lions, after Hawthorn opted to recruit St Kilda ruckman Ben McEvoy last week.

"We continue to have conversations with him and his manager to convince him that Brisbane's the place where his football future lies," Kerr said.

"No doubt some other clubs will more than likely express interest in him given the Hawthorn move fell over, but we're doing our best to try and keep him in Brisbane colours.

"I think he's really getting his mind around what's happened, because as far as he was concerned he was going to Hawthorn."

Patrick Karnezis wants to return to Victoria, but Kerr admits that move isn't definite.

"Collingwood's the club that's shown that interest there, but if I'm to be honest, I'd say it hasn't been strong interest."
