SATURDAY'S blockbuster clash between Richmond and Collingwood is officially a sell-out.

The AFL confirmed on Thursday that there were no tickets left for the game at the MCG. 

It added there will be "very limited" general admission seating and standing room spots available on game day for members who don't have a reserved seat and general admission ticket holders to access.

Earlier this week the MCG was predicting a crowd of 86,000 while the League had forecast a turnout of between 80,000-85,000 fans.

That would fall short of the record crowd for a home and away game attendance between the sides, which was set in 1977 when they played in front of 92,436 on Anzac Day. 

The AFL said if the stadium reaches capacity only reserved seat members or patrons with an issued ticket will be granted entry. 

Possible showers and a top of 16 degrees has been forecast for Melbourne's weather on Saturday.
