Scans have cleared exciting Saints youngster Max King from an ACL scare while playing for Sandringham on Sunday.

Last year's pick No. 4 came off the ground with a knee problem in the second quarter after landing awkwardly in a marking contest

It was the same knee that required a full reconstruction last year after rupturing his ACL.

However, Saints football chief Simon Lethlean confirmed that the injury was nothing serious.

"Looks like it's more, in my terminology, just a jarred knee and no disruption to the previous graft, so pretty positive.

"His parents [who were in attendance] were pretty emotional and concerned, as was he."

The 18-year old was playing in his fifth VFL game since returning to the field and had started the game well, kicking an early goal.

Lethlean added that while serious damage has been avoided, King was unlikely to play next week.
