St Kilda superstar Nasiah Wanganeen-Milera could find himself in hot water with the AFL after flipping the bird towards heckling fans on Sunday.

The league’s first $2 million man had a solid night but it wasn’t enough for the Saints, who went down 12.11(83) to 8.13(61) against the Western Bulldogs.

The defeat saw St Kilda lose touch with the top eight and frustration clearly took over Wanganeen-Milera when he left the field late in the match.

The 23-year-old seemed to be copping some words from the Marvel Stadium crowd when he ran off and gave them the middle finger as a response.

Saints coach Ross Lyon had little issue with it but admitted the AFL could see it differently and didn’t rule out Wanganeen-Milera being sanctioned.

“I didn’t even know it happened,” he said post-game.

“I think they were giving it to Nas and Nas was frustrated. I don’t know, we like a bit of theatre. Do we like the bird? We’re about to find out.”

The loss came at a price for the Saints as well, with three players – Tom De Koning, Jack Sinclair and Rowan Marshall – leaving the field with injuries.

Lyon remained upbeat in regards to De Koning and Marshall but was less certain about Sinclair.

“TDK and Rowan precautionary … I haven’t had an update [on Sinclair],” he said.

“There’s speculation that it’s an Achilles, but I’m not in a position to comment any further … Rowan should be fine and TDK is precautionary.”

Marcus Bontempelli had 34 disposals and seven tackles for the Bulldogs, who cemented their spot in the finals picture with the gritty win.

St Kilda will take on Essendon next Sunday, while the Dogs travel to face the Sydney Swans on Friday night.
