Max King is on track to slot straight back into the line-up for Sunday's Gather Round clash at Norwood Oval after seeing out his one-game suspension.

The key forward is a confirmed starter for St Kilda's match against Richmond pending he gets through tomorrow's training session, with experienced ruckman Tom Campbell and first-year pair Lance Collard and Hugo Garcia named on the extended interchange.

Campbell, Collard and Garcia all pieced together strong performances in last Sunday's VFL win over Essendon, with Collard a particular highlight through his four goals which propelled his side to a 38-point win.

Marcus Windhager is the only confirmed omission after receiving a one-game suspension for rough conduct on Essendon's Sam Durham last weekend.

St Kilda's final side for Round 4 will be confirmed tomorrow evening at 5:00pm AEDT.

IN: Campbell, Collard, Garcia, King
OUT: Windhager (suspension)
