Boston Celtics centre Al Horford will not exercise his $30.1 million player option and become an unrestricted free agent, according to ESPN's Adrian Wojnarowski.

Though he'll reportedly become a free agent, that obviously doesn't shut the door on Horford possibly returning to Boston. Wojnarowski reported earlier on Tuesday that both Horford and the Celtics have interest in reaching a new deal next month, but the insider has since reported the two sides are now too far apart on negotiations to believe that can in fact strike a deal. Wojnarowski adds that Horford is prepared to seek a three or four year deal with another clubs.

Horford averaged 13.6 points, 6.7 rebounds, and 4.2 assists per game over the course of the 2018-19 NBA regular season with the Celtics. The 33-year-old played nine seasons with the Atlanta Hawks before signing a four-year $113 million contract with the Celtics in July 2016.

The five-time NBA all-star has averaged 14.1 points and 8.4 rebounds in 786 career NBA games.
