The 2014 fixture will be unveiled in full on Thursday morning, but there has been speculation the AFL could introduce up to three Sunday night games as a trial next season, replacing the twilight fixture for those rounds.

With Thursday and Monday night games expected to remain next season, Riewoldt said players would need to come to terms with another new timeslot.
"From a player's point of view, it’s tough waiting around until Sunday midday to play your game of footy for that round," he said.
"I think waiting around until Sunday night, waiting until that 7pm timeslot, is going to be a tough one for the players.
"But I think we’ve seen in the past when the AFL decides to do something then they’ve gone and done it.
"The AFL is obviously delving into new frontiers as far as how they show the game and broadcast the game to fans."
Moving into the high-rating Sunday night timeslot makes commercial sense for the League, Riewoldt said, and it would likely help the next TV rights agreement.
However, the star goalkicker said the AFL would need to schedule high-rating games for the experimental fixtures.
"The biggest point is a lot of the games that are on these Sunday afternoons … haven’t been high rating games," he said.
"They haven’t been huge games that have been attended by the public.
"If they go down the Sunday-night path, they have to get the crowd in there, they have to get the atmosphere, otherwise we could really see it really petering off early in the season."
