Greater Western Sydney ruckman Shane Mumford is set to play on on 2021 in a player-coach role with the Giants.

The club will be looking to lengthen their ruck stocks following the retirement of Sam Jacobs, with Mumford's future also up in the air.

The Giants are believed to have offered the 34-year-old the role that will allow them to retain their ruckman while he can also transition into a mentoring position.

“It’s clearly more appealing because of the soft cap reduction,” Tom Morris told Fox Sports News’ AFL Tonight.

“They’re trying to bring on a couple of young ruckmen in Kieran Briggs and Matt Flynn, but they also want an older head to be there as well.

“Whether he plays too many games, I’m not sure. But they want him, at this stage, to be a development coach and a bit of insurance in the ruck department.”

The Giants are believed to be chasing departing Demon Braydon Preuss in the upcoming trade period as they look to improve on an underperforming 2020 season.
