Melbourne have taken the precautionary step of quarantining Simon Goodwin from the player group after the coach woke up on Friday morning feeling ill.
Goodwin was scheduled to hold a press conference before team training at Joondalup on Friday, but was told to stay in the team hotel as a precaution.
Assistant coach Adam Yze also fell ill and was told to remain at the team's hotel.
A number of Geelong players were struck down by sickness in the lead-up to their 83-point preliminary-final loss to the Demons.
Melbourne are taking every precaution to ensure the same situation doesn't occur to them.
"He (Goodwin) woke up a little bit crook, both him and Yze," Demons assistant coach Troy Chaplin said.
"They'll be fine come tomorrow, but the club didn't want to take any risks, and the doc just said to stay back.
"That's always a concern (that it could spread), but at the moment it's just those two boys who have woken up a little bit ill.
"All the players are going to be alright today, and they're all here.
"Given the stakes at hand, it's important we don't have something that sweeps through the whole club, so the doctors are just playing it really safe."
