McCall agrees new deal at Sarries
The former Ireland international, 45, joined Saracens in 2009 as first team coach and took over as rugby director when Brendan Venter left the role in January 2011.
McCall, who previously had a spell in charge of Ulster, picked up the baton seamlessly and guided Saracens to their first Aviva Premiership title with victory over Leicester in May of that year.
