THE AFL and Sydney are aware of serious allegations made on social media against first-year Swans player Elijah Taylor.

The allegations were made on Saturday night by the woman who was involved in Taylor's breach of COVID-19 protocols last month, which saw him banned for the remainder of the season. 

The social media post about the alleged incident has since been taken down. 

In a statement released on Saturday night, the Swans said: "The Sydney Swans are aware of allegations made on social media regarding first-year player Elijah Taylor. 

"The allegations are very serious and are being treated as such. 

"The club has notified the AFL and is not in a position to comment further at this time."

The AFL confirmed on Sunday afternoon that it had been notified of the allegations. 

"The allegations are extremely serious. The AFL has been in contact with local law enforcement and will continue to provide support and assistance for all. 

"Due to the nature of the allegations the AFL will be providing no further comment at this time." 

Taylor, 19, was selected at pick No.36 in the 2019 NAB AFL Draft. He made his debut in round seven against Gold Coast, and has played four games to date. 

He was banned for the remainder of the AFL season on August 15 after he brought a woman back to the Swans' quarantine accommodation in Western Australia when not authorised to do so.

It was a breach of not only the AFL's return to play protocols but also the Western Australian COVID-19 quarantine directions that applied to all Sydney players and officials at their quarantine accommodation. 

In addition to Taylor's ban, the Swans were fined $50,000, with $25,000 suspended.
