Newcastle back row trio Brent Wilson, Eni Gesinde and Ed Williamson have all extended their stay at Kingston Park by signing new contracts.
Former New Zealand Sevens international Wilson, 25, has signed a two-year deal, as has Williamson, with academy product Gesinde signing up for three years.
"Brent has taken his chance well this season and has plenty of rugby left," said forwards coach Peter Walton.
"Eni has burst onto the scene with a string of outstanding performances."
