St Kilda forward Paddy McCartin will miss at least one week after suffering his third concussion this season on the weekend.
McCartin was concussed when he was hit in the head during a marking contest in the first quarter of the Saints' loss to the Suns on the weekend.
St Kilda football manager Jamie Cox confirmed that the 20-year-old will miss this week's clash with Essendon at Etihad Stadium, and potentially longer.
"He's recovered well from the weekend," Cox said.
"At this stage, we've already made the decision that Paddy will miss this week's football, which will give us a chance to do all the necessary medical tests on Paddy, and give us a much better idea about when Paddy's ready to return to play."
McCartin suffered concussions in Round 3 against the Pies and Round 11 against the Crows.
