St Kilda Football Club advises Ben Paton and Nick Hind will join the squad in Shanghai ahead of Sunday's clash with Port Adelaide.

GM of Football Simon Lethlean said the addition of the two players was precautionary.

"We had three guys who felt ill on Friday afternoon and while they are recovering well, we wanted to cover all bases," he said.

“Speculation of a specific meal being the cause of these minor illnesses is completely false. As everyone knows, travelling overseas can present these challenges and we expect the players to be back to full health tomorrow.

"With Blake Acres already withdrawn from the team with a virus, it made sense to bring over Nick and Ben.

"At this stage, we expect both will be onlookers tomorrow.

Lethlean said coach Alan Richardson was expected to be back to full health.

"Like the players, Alan is just dealing with something fairly minor and recovering quickly."
