The AFL has invoked its extreme heat policy for Sunday afternoon's NAB Challenge match between Adelaide and West Coast at Unley Oval in Adelaide, reducing the quarters to 22 minutes and extending the breaks.

The mercury is expected to hit 36 degrees, with the match scheduled to start at 1:35pm ACDT.

The players will now have eight-minute breaks at quarter and three-quarter time and 25 minutes at half-time. There will be eight players on the interchange bench as per the rules in the opening two rounds of the pre-season competition. See all the rules for the 2016 NAB Challenge.
 
About half the tickets have been sold for Sunday’s game.

Eligible members* will have free General Admission access to their Club’s NAB Challenge matches, but entry is subject to capacity and is not guaranteed.

The AFL advises that Unley Oval has a limited capacity of approximately 10,000 and considering the anticipated demand for this match, strongly recommends that all members guarantee their entry by using their membership card to register for a general admission ticket via Ticketek.com.au.

Member registrations are subject to availability on a first come, first serve basis and subject to an additional fee. 

All NAB Challenge matches will be broadcast live on Fox Footy and the AFL Live App, which is offering a free trial pass. Radio station 1395 FIVEaa will also be calling the game.

See the Crows squad for Sunday’s match. The squad will be trimmed to 26 about 90 minutes before the opening bounce.

*Eligible members are Legends, AFC Season reserved seat, Essential Crows, Season GA, Victorian, Vic Home and Away and Interstate
