Boston Celtics big man Al Horford has decided he will not kick in the option he has for the final year of his contract with the C's and instead become an unrestricted free agent.

That's what league sources are telling ESPN.

Horford was due to earn $30 million dollars next season but there seems to be mutual interest in turning that one-year deal into a multi-year deal for less money per year.

That would help the Celtics salary cap situation and would guarantee Horford more money.

The 33-year-old power forward/center is a favorite of Boston coaches and players. He has been in the playoffs 11 times in his 12 year NBA career.

Last season he averaged 13.6 PPG and 6.7 RPG.

Horford officially becomes a free agent on June 30th.
