Sydney coach John Longmire has signed a new deal to remain at the Swans, turning down a lucrative offer to take over the vacant position at North Melbourne.

The Swans on Friday confirmed Longmire has extended his contract for a further three years, tying him to the AFL club until the end of 2023.

It is a major blow for the Kangaroos, who had hoped to lure Longmire – a favourite son and premiership player – back to Arden St to replace Brad Scott.

Longmire’s decision could also benefit North caretaker Rhyce Shaw, who is building a strong case to take over the Kangaroos role permanently.

Sydney’s longest-serving coach, Longmire has overseen 191 games and led the Swans to the premiership in 2012.

“The job of the senior coach is a huge commitment from both sides, so it was important to take the time to ensure that I could continue to give the role the energy it needs,” he said in a statement.

“I’m really pleased that the club has the faith in me to continue and that I have the support of my family to continue.”
