The Clippers declined a $7.5 million team option on Zubac's contract, clearing the way to negotiate a new deal for Zubac, who is the longest-tenured player on the roster. Zubac, 25, is a frontcourt anchor on a starry Clippers roster expected to compete for an NBA championship next season.
Zubac had his most productive NBA season for the Clippers a year ago -- averaging career bests of 10.3 points and 8.5 rebounds. In his fourth season with the Clippers after coming over in a trade from the Lakers, Zubac started 76 games a season ago.
"For four seasons, Zu has been a pillar of our team, durable and dependable," Clippers president Lawrence Frank said in a statement. "We are excited to continue growing with him."
Zubac is the second Clipper to sign an extension since the end of the season, joining forward Robert Covington. Zubac has averaged 8.3 points and 6.5 rebounds in his seven-year NBA career.
