Ross Lyon has called on St Kilda players to stand up for Max King against physical attention from opponents as the young star works his way back from injury.
King focused on adding size to his frame after off-season shoulder surgery, which delayed his start to the AFL season.
The 22-year-old key forward kicked four goals on return in the 12-point win over GWS last round.
"He's put on some size and we knew he could do all the running," Lyon said on Wednesday.
"We just spoke about he probably needs a bit more support.
"We think key defenders are quite physical, they'll be physical on him."
Tim Membrey is a chance to return to add some muscle to the Saints' attack against Hawthorn at Marvel Stadium on Saturday.
But the experienced forward is still yet to tick all the boxes in his recovery from concussion.
"It's going smoothly but that could change with the wind, we know that," Lyon said.
Second-year forward Mitch Owens is recovering well from the head knock that led to him being carried off the ground during the Giants clash.
The 19-year-old, who was hurt by an accidental knee from teammate Anthony Caminiti, is a chance to return after the round 12 bye.
"He had no symptoms, according to the doctor ... so that was a good sign," Lyon said.
"We think he could've been a lot worse. If had've been kneed to the face he could've suffered some fractures, but he's tracking well."
St Kilda (7-3) sit fifth on the ladder but have not won consecutive games since round four.
