"Keyon has decided that he has given the NBA 12 good years and that it's time to pursue other interests and spend more time with his family," said Dooling's representative Kenge Stevenson. "He will never forget his time in Boson with the Celtics."
Dooling averaged 4.0 points and 1.1 assists for the Celtics last season but had big moments off the bench for the club. He was also thought of as a great motivator in the locker room and was signed during the off season because of it.
The Celtics now have 13 guaranteed invited to camp. With Dooling out of the picture, this give the Celtics rookies, Kris Joseph and Dionte Christmas, who aren't guaranteed contracts, a chance to make the final roster before the start of the regular season.
