Sydney FC will have to beat Newcastle for the first time this season without Brett Emerton after the midfielder was ruled out of Saturday's A-League clash with back tightness.The Socceroos veteran was officially scratched on Thursday although the club hopes he'll make a quick recovery after scans cleared him of a hamstring tear from last weekend's 3-1 loss to Melbourne Victory.Yairo Yau will also miss the crucial clash at Hunter Stadium while on international duty for Panama.One-match suspensions to defenders Fabio and Tiago Calvano are set to clear the way for Adam Griffiths' recall and a first in the competition.If Adam plays alongside teammate Joel and against younger brother Ryan, it will be the first time three brothers have appeared in the same A-League match.The match will be an intriguing battle between two of the competition's top strikers, Alessandro Del Piero and Emile Heskey, while the Sky Blues (20 points) can leapfrog fifth-placed Newcastle (22) with a win.The Jets have won both encounters between the two sides this season, 3-2 in Sydney and 2-1 in Newcastle.
