The AFL is set for another fixture reshuffle with the chaos of round 20 set to have a flow-on effect into round 21.
Essendon are set to play the Western Bulldogs but their game is expected to be pushed back from its original Friday night timeslot.
Delaying the Bombers' round 20 clash with Sydney from Saturday night to Sunday means there would only be a five-day break between games if they played on Friday.
Clubs are only allowed to have one five-day break in the season - as per the AFL Players' Association's agreement with the league - and Essendon had theirs between rounds three and four.
"Yes (our opponent is) still the Dogs, I'm pretty sure. But ... we haven't got any certainty on when that'll be," coach Ben Rutten said.
"Obviously things got tipped on the head yesterday so we'll wait and find out.
"Hopefully we'll find out in the next 24 hours, about when we're playing, but we'll be able to prepare for that game."
