St Kilda's Nasiah Wanganeen-Milera and Port Adelaide's Jase Burgoyne have both been subject to online racial abuse following their respective matches on Sunday.
Both players posted screenshots to their Instagram stories on Sunday night, revealing messages they received from anonymous trolls.
The messages from the two separate accounts were littered with racial abuse and a frustration with the game statistics of both Wanganeen-Milera and Burgoyne, which is believed to have stemmed from gambling results.
Wanganeen-Milera captioned his social media post: "Over a game of football. Hero mate", while Burgoyne posted a clown emoji over his.
The messages to Wanganeen-Milera followed his side's narrow defeat to Sydney on Sunday afternoon at Marvel Stadium, while Burgoyne and Port Adelaide claimed a win at home over West Coast later in the day.
St Kilda CEO Carl Dilena hit out at the "abhorrent" messages ent to Wanganeen-Milera.
“As a club we do not accept racist behaviour of any kind. These comments are abhorrent and have no place in our game or our community,“ the Saints boss said in a statement.
“Beyond Nasiah's talent on the field, he is a proud Kokatha and Narangga man who deserves to work and live free from this type of abuse. St Kilda Football Club stands firmly with Nasiah, his family and all First Nations people, and we remain committed to fostering a safe and inclusive environment for everyone.
“We fully support Nasiah and will work closely with the AFL Integrity Unit to do everything we can to identify the person responsible for these messages.“
Port Adelaide released a similar statement on Monday.
"Port Adelaide Football Club is aware of -- and condemns in the strongest possible way -- racist abuse directed at Jase Burgoyne following last night's game against West Coast and abuse directed at a fellow First Nations player within the AFL competition," the statement read.
"Such abuse is reprehensible and will not, and should not, be tolerated.
"The club has advised the AFL integrity department and we look forward to working closely with the AFL to identify those responsible and sanction appropriately.
"We also encourage people who witness or experience online abuse to report and highlight it to the social media platforms on which it appears.
"Port Adelaide also calls for Governments to demand accountability from social media organisations. Platforms need to take accountability and action against these abusers.
"Port Adelaide stands united with Jase and all First Nations players across the competition who have been subjected to racism.
"As a club with deep community roots and strong connections to diverse communities, we will continue to use our platform to call out racism wherever it occurs.
"Racism and hate have no place online, at our venues, or in our community."
The latest cases of online abuse towards AFL players follow Burgoyne's teammate Willie Rioli, who faced racial vilification in April this year.
Brisbane co-captain Lachie Neale took to social media later that month to condemn trolls, who he stated are "the biggest stain on society" and "cowards".
"People hiding behind keyboards to attack players are the biggest stain on society," Neale wrote on Instagram.
"It's getting beyond a joke now, the things I've seen sent are some of the most horrific messages I've ever seen.
"It's a game of football, grow the f**k up. Cowards.
"Put your face and name to your words."
The AFL Integrity Unit has been made aware of the recent messages sent to Wanganeen-Milera and Burgoyne.
