London - Saracens director of rugby Mark McCall signed a contract extension with the English Premiership champions on Tuesday.
McCall put pen to paper on the new deal three days after leading Saracens to their fourth Aviva Premiership title with a final victory against Exeter at Twickenham.
He was joined in signing on for the long term by several of his Saracens coaching staff.
"It's great news that they have all re-signed. They're a team within a team; a group of friends together - they're my friends," Saracens chairperson Nigel Wray said.
McCall joined Saracens in 2009 and took up his current position during the 2010/11 season, leading the club to the Premiership title.
The 50-year-old has helped steer Sarries to three Premiership crowns in total, as well as back-to-back European Cup triumphs in 2016 and 2017.
