After Sydney sat him out last week for a rest, Lance Franklin has returned to the Swans line-up to take on Essendon tonight.
Sydney, who had a five-day break between rounds three and four, felt it best to hold over the champion forward.
Hayden McLean has been omitted to make way for Buddy.
The Bombers have also been bolstered by the return of captain Dyson Heppell, who has missed with a back niggle.
Mason Redman comes out of the side after tearing his hamstring in Round 3.
