The Sydney Swans will be without ruckman Kurt Tippett and defender Callum Mills for Saturday’s semi final against the Adelaide Crows at the SCG.



Scans have revealed Tippett suffered a non displaced, hairline fracture to his jaw in last night’s match against GWS.



He will consult a specialist on Monday to determine the best course of action.



Meanwhile Mills, who left the ground injured during the second quarter, has also had scans which have revealed a grade one (lowest grade) hamstring strain.
