The Adelaide Oval has decided to open its gates to footy fans and members of the public today to allow tributes to Adelaide Crows coach Phil Walsh.

Walsh was to coach his 13th game of AFL against Geelong on July 5 at 2.50pm.

The South Gate on the Telstra Plaza will open at 2.30pm and entry is free.

The Oval will sound the siren at 2.50pm as was originally scheduled before the cancellation of the Crows-Cats game. Patrons will then be invited to enter the arena if they wish to have a kick-and-catch on the oval.

The stadium will close at 4pm.
