Aberdeen manager Derek McInnes and assistant Tony Docherty have agreed new contracts that will keep them at Pittodrie until summer 2020.
The former St Johnstone and Bristol City boss has been in charge since replacing Craig Brown in the spring of 2013 and guided the Dons to runners-up spot in three competitions last season.
He told the club website: "I am committed to trying to bring more success to the club - with the excellent squad of players and the backing of our brilliant supporters, it is important we keep driving forward both on and off the pitch and maximise our full potential."
