A FIRE has been contained at Domain Stadium just hours before Sunday night’s game between Port Adelaide and Fremantle.

An explosion was heard inside the stadium before smoke was seen coming out of a hospitality area inside the stadium.

That location is on the opposite side of the stadium from the Power's changerooms and players' race. 

Local fire services raced to the Subiaco arena to contain the blaze, which was found to be inside one of the stadium’s hospitality kitchens.

Sunday night’s game - also expected to be a fiery encounter as a re-match of last year's semi-final will continue as scheduled.
