North Melbourne defender Ben McKay has been stretchered off against Brisbane.
McKay copped a knock to the head in a collision in the third term.
Play was stopped for several minutes as the North doctors attended to him.
McKay was making his AFL debut.
The 19-year-old was selected with pick 21 in the 2015 AFL draft.
He had racked up nine disposals up to three quarter time.
