THE AFL has made multiple changes to the round 20 fixture with an under-siege Carlton returning to primetime for the first time since round two. 

The Blues will take on St Kilda at Marvel Stadium on Friday night with the Bombers' season-defining clash with the Swans moved to Saturday night and to be played at the Gabba. 

A venue for Gold Coast v Melbourne and Greater Western Sydney v Port Adelaide is still to be determined, but Tasmania will host two games this weekend.
