SYDNEY coach John Longmire has expressed his frustration that footage of a distraught Paddy McCartin was shown live during the Swans' win over Hawthorn.

The reborn defender was captured by cameras in the Swans' rooms after he was subbed out of Monday's game with concussion.

McCartin has a long and torrid history with head knocks, and the former No.1 draft pick's career at St Kilda was cut short because of them.

The 26-year-old has only returned to the AFL this year after spending a season with the Swans' VFL side.

McCartin will miss Sydney's blockbuster clash with Brisbane on Sunday due to the AFL's 12-day concussion protocols.

But Longmire believes it was irresponsible for Fox Footy to broadcast footage of McCartin immediately.

The 2012 premiership coach will consider raising the issue with the AFL and broadcasters.

"(McCartin's) feeling fine," Longmire said on Wednesday.

"The complicating factor with Paddy was probably the vision and what the vision doesn't provide is context or background and leaves things open for interpretation without knowing the facts behind it.

"The reality was he felt fine, even though some people probably jumped to conclusions during the course of the game.

"He was just disappointed he couldn't get back out on the ground, first of all, then he knew it would rule him out for this week.

"I think if you understand the context of what he's been through then that's understandable.

"Personally, I don't think vision should be shown at half-time in those situations.

"I saw (Port Adelaide star) Ollie Wines was wired up and had a few issues, but no one knew about it and I don't think that should have been shown as well.

"I think that's an issue for the AFL Players Association to take up.

"It's about players' family, and friends and a whole network of people watching that as well.

"He felt terrific, his emotions were purely based on the fact he was ruled out of the game and will miss this week.

"You can understand there's a bit of anxiety with Paddy when he goes into that process from what he's been through."

Young forward Logan McDonald also suffered a concussion during the come-from-behind win against the Hawks and will miss this weekend.

Veteran tall Sam Reid looks set to come back into the side to replace McDonald.

Dynamite forward Tom Papley remains on track to play his first game of the season after suffering a hamstring injury in a practice match last month.
