Championship-winning duo Matt Knight and Jesse Wagstaff have re-signed with the Perth Wildcats, but centre Tom Jervis has left the NBL club.

Knight has signed a new two-year deal, while Wagstaff's new deal will tie him to the club for the next three seasons.

The Wildcats were dealt a blow on Monday when centre Jervis confirmed he had signed for the Brisbane Bullets on a three-year deal.
