Northampton Saints pair James Fish and George Furbank have signed new deals with the Premiership side until 2021.
Hooker Fish, 22, has made 16 first-team appearances for the club, having made his debut in the 2016-17 campaign.
Full-back Furbank, 22, also came through Northampton's academy and has made six starts this term.
"It's really important to see academy players successfully make the transition from age-group rugby to the wider squad," said boss Chris Boyd.
