The defending champion Celtics continued to pursue roster stability, reaching a multiyear agreement with big man Neemias Queta, Shams Charania of The Athletic reports.

Boston made Queta a restricted free agent on Saturday by extending a qualifying offer of approximately $2.37M. That came after the club declined its team option on his contract.

Queta averaged a career highs of 5.5 points and 4.4 rebounds and 0.8 blocks per night with the Celtics across 28 contests, earning a promotion from his two-way contract to the 15-man roster.

He was not part of the club’s rotation during its title run, appearing for cameos in just three contests.

The Celtics also reached a one-year agreement with another of their backup big men, Luke Kornet. That depth should come in handy with starter Kristaps Porzingis sidelined five to six months after undergoing left leg surgery.
