Sydney Swans senior coach John Longmire has hailed his young talent for stepping up under pressure, as the Swans snatched an 11-point victory over North Melbourne at the SCG.

The Kangaroos appeared on track for victory after kicking the opening goal of the final term to stretch their lead to 14-points, before Isaac Heeney and Justin McInerney delivered in the final moments.

“It’s a great sign when it’s your younger players are the ones that are able to turn the momentum. It’s really important that the responsibility isn’t just on the older ones that have done it for a long time,” said Longmire.

“There were some really important individual efforts which helped but we don’t want to rely upon that. (Oliver) Florent particularly during the second half of the game was good, (Justin) McInerney was good, (Isaac) Heeney’s last quarter, there were a few that were able to really get going in the last 25 minutes of the game.

"When we hit our strides in the last quarter and played with that level of energy that we know we can we were able to get the game back on our terms.”

Longmire admits it was pleasing to see his side swing the momentum late, following a tough first half against a fired up Kangaroos outfit.

“We weren’t playing that well in the first half, and we knew we didn’t have the energy that North Melbourne was showing. They were really going well, and a lot was going right for them,” said Longmire.

“You have to give credit to the opposition, they were good. They turned up and were really hungry for the contest. At three-quarter time they had a bit of momentum, but we were able to fight back at different times.

"You can’t underestimate your ability to get your nose over the line, to have that run and energy in the last quarter and keep our foot down right until the end of the game was really important.”

Lance Franklin was forced to watch the final quarter from the sidelines after suffering a finger injury during a contest in the third term.

“It looks like he’s broken his finger, we’ll see what the specialist says on Monday," said Longmire.

“He’s okay, he doesn’t like missing footy make, no mistake about that, but after 18 years of footy he understands that these things happen. He just went into a tackle there and hit his finger, he’ll be fine.”

Paddy McCartin was cleared to return to the field after a nasty collision halfway during the final term.
