He guided Saints to victory in the 2019 Premiership Rugby Cup and they also reached the league play-off semi-finals in the same year.

They are currently fifth in the Premiership, but have lost both games so far in the European Champions Cup.

Boyd joined Northampton from New Zealand side Hurricanes, who he led to the Super Rugby title in 2016.

He initially signed a three-year contract at Franklin's Gardens, but agreed a new deal in November 2020 to run until the end of the 2021-22 season, and it remains a possibility that he could retain links with the club as a consultant.

The club's board will now decide whether to promote assistant coaches, Phil Dowson and Sam Vesty, and a decision is expected later this week.

After reaching the play-offs in 2019 before losing to Exeter, Saints have finished eighth and fifth in their past two Premiership campaigns.
