Ex-Magpie defender on Saints’ radar
Nathan Brown is also suspended for Round 1.
Clubs have the opportunity to add a player that is out for the season by this Friday, with the new pre-season supplemental selection period to close at 5pm on March 15.
Marsh, 23, will be put through a medical but is considered a real chance of lining up for the Saints in round one..
The former Pies defender spoke late last year of his desperation to return to the AFL, having stepped away from the game at the end of 2016 after 15 games to deal with his mental health.
"I'm 110 per cent in," he said in November.
"I'm fully committed. That's why I've been doing the work when nobody's watching because I'm so desperate for that second chance. I'm that keen for it that it's quite remarkable."
He said he was proud of his decision to walk away from the game and make his mental health a priority.
