The AFL preliminary finals controversy appears over, with the league and the MCG confident of a deal after Wednesday's two-hour meeting.

Adelaide chief executive Steven Trigg hailed the breakthrough as a big win for the "integrity" of the competition.

AFL commission chairman Ron Evans and MCG Trust chairman John Wylie emerged from the meeting to confirm their bodies had moved much closer to a resolution.

Evans was confident the deal would be formalised next week.

It is expected that the revised arrangement would be in place for this year's finals series.

"We have had a very productive and constructive meeting, we believe that we have the semblance of an agreement," Evans said.

"We're going to take the details back to our respective boards (and) we expect to meet again probably next week to attempt to finalise the matter."

Wylie added: "We believe we are very close to an agreement, so we are very pleased."

Under the current agreement between the two bodies, the AFL must play at least one of its two preliminary finals each year at the MCG.

That meant Brisbane had to "host" its preliminary final against Geelong last year at the ground.
