The AFL may consider moving Geelong's round 21 clash with Richmond from Simonds Stadium to the MCG if the form of both teams continues over the next 10 weeks.

In a time when momentum is building for the Cats to be handed a home final at Kardinia Park, the club could be stripped of a home-and-away game if circumstances call for it.

The match, scheduled for August 12, is one of seven games fixtured at Simonds Stadium, the majority of which will be in the back half of the year due to the venue's recent redevelopment.

But, with Geelong third on the ladder and Richmond fourth, the game could potentially draw a crowd double the size of Simonds Stadium's capacity of 36,000.
